Curved treadmill benefits: why they're taking over functional gyms
Walk into a modern CrossFit box, a Hyrox training facility or a serious functional-training studio today, and you'll almost certainly see a curved treadmill — a manual, motor-free running machine with a distinctive concave deck. A few years ago these were a novelty; now they're becoming a fixture, and in many functional gyms they're replacing the motorised treadmill entirely. That shift isn't a fad. It's driven by a genuine set of advantages that suit the way modern athletes and gyms actually want to train: harder conditioning, better running mechanics, lower injury risk, and equipment that survives relentless use without an expensive motor to break.
This guide explains exactly why curved treadmills are taking over — what they are, how they work, and the full set of benefits that make them so well-suited to functional training. We'll compare them honestly to motorised treadmills, cover who should use one and how, walk through the ATE curved treadmill range (the C1, C1 Pro and X1 Pro), and answer the questions buyers actually ask. Whether you're kitting out a CrossFit box, a Hyrox facility, a performance gym or a premium home setup, by the end you'll understand precisely why the curved treadmill has earned its place — and whether it's right for you.
TL;DR — why curved treadmills are winning
A curved treadmill is self-powered — you drive the belt with your own feet, so there's no motor and no electricity. That single design choice delivers the benefits functional gyms want: you burn up to ~30% more calories than a motorised treadmill, the machine self-scales to your effort (perfect for sprints and HIIT), it improves running form, engages more muscle, is gentler on the joints, and — with no motor — it's near-indestructible and virtually maintenance-free, running silently with zero running cost. That combination of harder training and bombproof durability is why boxes, Hyrox gyms and performance facilities are adopting them fast.

What is a curved treadmill?
A curved treadmill is a manual, self-powered running machine with a concave (curved) running surface, built from a series of slats rather than a single flat belt. Unlike a conventional treadmill, it has no motor and needs no electricity — the belt is driven entirely by your own movement. You start it, speed it up, slow it down and stop it purely by where and how you run on the curved deck. There are no buttons to set a speed; your feet are the engine.
The defining feature is the curve. The running surface arcs upward at the front and back and dips in the middle, and that shape is what makes the whole thing work: it lets gravity and your foot placement control the belt speed, and it naturally encourages a proper running posture and foot strike. The slat belt — individual slats over low-friction bearings, cushioned with a durable material — glides smoothly and absorbs impact. On ATE's Curved Treadmill C1, those slats are thermoplastic-elastomer (TPE) for a smooth, joint-friendly glide; on the premium C1 Pro and X1 Pro, they're durable aluminium slats for a frictionless feel at high speed.
Because the runner powers everything, a curved treadmill delivers a fundamentally different — and for many purposes, better — workout than a motorised machine. That's the root of every benefit we're about to cover.
How a curved treadmill works (the mechanics)
Understanding the mechanics makes the benefits obvious. Here's what's happening under your feet.
On a motorised treadmill, an electric motor spins a flat belt at a speed you set, and you keep up. The machine does the work of moving the belt; you just match its pace. On a curved treadmill, there's no motor — instead, the curved deck plus gravity plus your foot placement drive the belt. When you step onto the front, higher part of the curve and push back and down, your body weight and drive move the slat belt beneath you. Run higher up toward the front of the curve and you go faster; drift back toward the flatter, lower centre and you slow down; stand still in the middle and the belt stops. Speed is entirely, instantly and infinitely controlled by you.
The slats on low-friction bearings let the belt move smoothly with minimal resistance, while the curved geometry means you're always working against gravity and your own inertia — there's no motor helping you along. Some curved treadmills, including ATE's C1 and C1 Pro, add a magnetic resistance control (8 intensity levels) so you can crank up the difficulty for sprint and strength-endurance work on top of the base effort. The net effect: every second on a curved treadmill, your muscles are doing 100% of the work of both moving your body and moving the belt, which is exactly why it's so much more demanding — and so much more effective — than a motorised belt.
Why functional gyms are adopting curved treadmills fast
Before the benefits list, it's worth naming why this is a trend, not just a feature. Functional gyms — CrossFit boxes, Hyrox facilities, performance and hybrid-training studios — have specific needs that curved treadmills meet almost perfectly, and that motorised treadmills meet poorly:
- They program sprints and intervals, not steady jogs. Functional training lives on high-intensity intervals, and a curved treadmill lets an athlete go from a dead stop to an all-out sprint and back instantly, with no lag while a motor spins up or down. That responsiveness is transformative for HIIT.
- They want maximum conditioning per minute. Because you power it, a curved treadmill is simply harder — more calories, more effort, more conditioning in less time. That fits the intense, time-efficient ethos of functional training.
- They put equipment through relentless daily abuse. A motor is the most expensive, most failure-prone part of a treadmill. Remove it and you get a machine that survives being sprinted on all day, every day, with almost nothing to break — ideal for a busy box.
- They don't want to run wiring or pay for power. No electricity means you can place a curved treadmill anywhere, add several without electrical work, and pay nothing to run them. For a facility with a bank of them, that's real money and flexibility.
- They increasingly train Hyrox and hybrid formats. Running is central to Hyrox and hybrid fitness, and the curved treadmill's self-paced, form-improving, sprint-friendly nature suits that training exactly.
In short, the curved treadmill matches the training style, the durability demands and the operating economics of the functional gym better than any motorised machine — which is why adoption has accelerated. Now let's go through the benefits that drive it.
The benefits of a curved treadmill, in detail
Here's the full case, benefit by benefit — the reasons a curved treadmill outperforms a motorised one for functional training.
1. You burn significantly more calories
This is the headline benefit. Because you power the belt instead of a motor, every stride costs more energy, so a curved treadmill burns meaningfully more calories than a motorised treadmill at the same perceived pace — commonly cited at around 25–30% more. For anyone training for fat loss or conditioning, that's a huge efficiency gain: more work done, more calories burned, in the same or less time. It's exactly why ATE describes the curved design as delivering "a higher intensity workout and more calories burned in a shorter amount of time." If your goal is maximum conditioning per minute, the curved treadmill is simply the harder, more productive tool.
2. Unlimited, self-paced speed — perfect for HIIT and sprints
On a motorised treadmill, changing pace means pressing buttons and waiting for the belt to spin up or down — useless for true intervals. On a curved treadmill, your footwork sets the tempo instantly: you can explode into an all-out sprint and come to a complete stop in a single step, with no lag and no controls. That responsiveness makes it the ideal machine for HIIT, sprint intervals, Tabata and any interval format — the reason it's a fixture in functional and athletic training. As ATE puts it, "gone are the days of preset speeds — your footwork sets the tempo." There's effectively no speed limit either; the machine is exactly as fast as you can run.
3. It improves your running form
The curve does something a flat belt can't: it rewards good running mechanics. To run efficiently on a curved deck you have to land on your midfoot/forefoot under your centre of mass, stay tall, and drive properly — heel-striking and poor posture simply don't work well on the curve. Over time this trains a cleaner, more efficient, lower-impact running technique that carries over to outdoor running and sport. ATE notes that the curved design "promotes proper posture and foot strike," which "helps improve running form and reduce the risk of injuries." For athletes and coaches, that form-correcting quality is a major reason to choose curved.
4. It engages more muscle
Running on a curved treadmill recruits more muscle than a flat belt. The natural upward curve acts like a constant slight incline, so you engage more of the posterior chain — glutes, hamstrings and calves — on every stride, and because you're powering the belt yourself, the legs work harder throughout. ATE highlights that "the incline of the curved treadmill engages more muscle groups, providing a comprehensive workout that benefits the entire body." More muscle engaged means more work, more calories, and a more athletic training stimulus than jogging on a motorised belt.
5. It's gentler on the joints
Despite being harder work, a good curved treadmill is kinder to the joints. The cushioned slat belt — TPE slats on the C1, aluminium slats with low-friction bearings on the Pro models — absorbs impact and reduces the strain on knees, ankles and connective tissue compared with running on the road or a hard surface. ATE describes the slats as "effectively absorbing impact and minimising strain on joints and connective tissues," making the curved treadmill "an excellent choice for those with joint concerns or those looking to minimise the risk of injury." You get intense conditioning with lower impact — a rare and valuable combination.
6. It's safer — no runaway belt
A subtle but important safety benefit: with no motor, there's no belt that keeps moving if you stumble. On a motorised treadmill, a trip can be dangerous because the belt drives on regardless. On a curved treadmill, the belt only moves when you move it — slow down and it slows, stop and it stops. That makes it inherently safer, especially for high-intensity sprint work where a fall on a powered belt is a real risk. It's one reason coaches are comfortable programming all-out efforts on them.
7. Near-indestructible with almost no maintenance
Here's the benefit gym owners love. The motor, motor controller board and drive electronics are the most expensive and most failure-prone parts of a motorised treadmill — and a curved treadmill has none of them. With no motor to burn out, no board to fail and no belt-motor to service, there's dramatically less to go wrong, and the machine survives relentless daily sprinting that would wear out a motorised treadmill. ATE's curved treadmills are built on a heavy-duty commercial frame (around 175 kg) with low-friction ball bearings for years of smooth, low-maintenance performance. For a busy commercial floor, that durability and low upkeep is a decisive advantage.
8. Zero electricity, zero running cost, place it anywhere
Because it needs no power, a curved treadmill costs nothing to run and can be placed anywhere without wiring — you can add a whole row without electrical work, and there's no power bill from running them all day. It's also eco-friendly (no energy consumption) and silent (no motor noise), which improves the training environment. ATE notes the curved design "does not require electricity — saving on energy costs and reducing your carbon footprint." For a facility, the combination of no install constraints, no running cost and no noise is genuinely liberating.
It gives you more of everything you want from conditioning — calories, intensity, muscle engagement, form, sprint responsiveness — and removes the motor, which is the treadmill's most expensive, most failure-prone, most costly-to-run part. Harder training and lower total cost of ownership. That's the whole reason it's taking over functional gyms.
Curved treadmill vs motorised treadmill
To be fair and complete, here's an honest head-to-head. Both have their place — the right choice depends on how you train.
| Factor | Curved treadmill | Motorised treadmill |
|---|---|---|
| Power | Self-powered, no electricity | Electric motor, needs power |
| Calorie burn | Higher (~25–30% more) | Baseline |
| Speed control | Instant, self-paced, unlimited | Button-set, motor lag |
| HIIT / sprints | Ideal | Poor (lag between speeds) |
| Running form | Improves it | Neutral / can mask poor form |
| Joint impact | Low (cushioned slats) | Low–moderate (varies) |
| Safety | No runaway belt | Powered belt keeps moving |
| Maintenance | Very low (no motor) | Higher (motor, board, belt) |
| Running cost | Zero | Ongoing electricity |
| Set-speed steady runs | Requires self-pacing skill | Easy, precise pace-holding |
| Incline / programs | Fixed curve, intensity levels | Adjustable incline & programs |
| Learning curve | Slight (takes a few minutes) | None |
The pattern: a curved treadmill wins decisively for functional training, HIIT, sprint work, calorie burn, durability and running cost, while a motorised treadmill wins for precise steady-state pacing, programmable incline sessions and absolute ease of use for beginners who just want to set a speed and walk. That's why many well-equipped facilities have both — curved treadmills for the conditioning and functional floor, and motorised for members who want steady, set-pace cardio. ATE builds both: the curved treadmill range and a full line of commercial motorised treadmills.
Honest downsides & considerations
No machine is perfect, so here are the genuine trade-offs to weigh:
- A short learning curve. The self-paced curve feels unfamiliar for the first few minutes — new users need a moment to learn how foot position controls speed. It clicks quickly, but it's not quite as instantly intuitive as pressing "start" on a motorised belt.
- Harder to hold a precise steady pace. If your goal is running exactly 10 km/h for 30 minutes, a motorised treadmill's set speed is easier. On a curved treadmill you self-pace, which is a feature for intervals but takes more attention for steady-state.
- No programmable incline or preset programs. The curve provides a fixed effective incline; you can't dial in a specific gradient or follow a built-in interval program the way some motorised consoles allow (though intensity levels add challenge on the C1/C1 Pro).
- Higher upfront price than a basic motorised treadmill. A quality commercial curved treadmill costs more upfront than an entry motorised machine — but with no motor to fail and no running cost, the total cost of ownership over years is often lower.
- It's demanding. Because you power it, it's genuinely hard work — a benefit for athletes, but worth knowing for very deconditioned beginners, who may prefer to start on a motorised machine.
None of these outweigh the benefits for a functional gym or an athletic user — but they're the reasons a motorised treadmill still makes sense for some buyers and settings, and it's only fair to name them.
Who should use a curved treadmill?
- CrossFit boxes & functional studios: the natural fit — sprint-friendly, durable, no-electricity conditioning that matches functional programming. See the CrossFit equipment range.
- Hyrox & hybrid-training facilities: running is central to Hyrox, and the curved treadmill's self-paced, form-improving, interval-ready nature suits it perfectly for run-conditioning stations.
- Athletes & performance coaches: superb for sprint training, conditioning, and building efficient running mechanics with lower impact — a genuine performance tool, not just cardio.
- Commercial gyms adding a conditioning zone: a durable, low-maintenance, no-power machine that differentiates the floor and gives members a harder, more engaging cardio option.
- Serious home & garage gyms: for a home athlete who wants intense conditioning, no electricity or wiring, silent operation and a machine that will never burn out a motor, a curved treadmill is a superb (if premium) choice. Browse the best sellers.
- Rehab & return-to-run (with guidance): the low-impact, form-correcting, self-paced nature can suit controlled return-to-running work under a professional's guidance.
The main exception: a very deconditioned beginner who just wants to walk at a set pace may find a motorised treadmill gentler and simpler to start with. For almost everyone training with intensity, though, the curved treadmill is the better tool.
Curved treadmill workouts to try
The curved treadmill's instant, self-paced speed makes it a superb interval machine. Three sessions to get started:
Sprint intervals
10 rounds: 15–20 seconds all-out sprint, 40–60 seconds walk/easy. Because you can hit top speed and stop instantly, this is the purest, most effective sprint-interval workout — brutal for conditioning and fat loss. Crank the intensity level (on the C1/C1 Pro) for extra resistance.
The functional conditioning piece
Pair the treadmill with other functional work: 5 rounds of a 200 m hard run, 15 wall-ball shots or slams, and 10 burpees. The curved treadmill's quick on/off makes it ideal for run-into-strength circuits — a staple of CrossFit and Hyrox training.
Steady-state base run
20–30 minutes at a controlled, conversational pace, focusing on a clean midfoot strike and tall posture. Builds aerobic base and grooves good running form — and even at "easy" effort you'll burn more than the same pace on a motorised belt because you're powering it.
Because the machine scales to your effort, every one of these works for a beginner or an elite athlete — you simply run harder.

How to choose a curved treadmill
If you've decided a curved treadmill is right for you, judge your options on these points:
- Slat material & feel. Cushioned TPE slats (C1) are smooth and joint-friendly; aluminium slats (C1 Pro, X1 Pro) give a frictionless glide at high speed and extra durability. Choose based on the running feel you want.
- Running area. A larger deck (e.g. 1700×480 mm) suits taller users, sprinters and safety; make sure it fits your tallest, fastest athletes.
- Resistance control. Magnetic intensity levels (8 on the C1/C1 Pro) let you add difficulty for sprint and strength-endurance work — useful for varied programming.
- Frame & capacity. A heavy-duty frame (ATE's ~175 kg) and a high user-weight rating (160 kg) mean stability under all-out sprints and commercial durability.
- Console. A clear LCD tracking time, distance, speed, calories and modes helps structure training.
- Build quality & bearings. Low-friction ball bearings and quality construction determine how smooth and long-lasting the ride is — buy from a genuine manufacturer.
- Warranty & support. A real warranty and local spares/service matter for a high-use machine — ATE offers a 2-year warranty with pan-India support.
Maintenance & durability
One of the curved treadmill's biggest practical wins is how little it needs. With no motor, no motor-control board and no drive electronics, the failure points that plague motorised treadmills simply don't exist. Upkeep is minimal:
- Wipe it down after use — sweat is the main enemy of any cardio machine.
- Keep the slats and bearings clean of dust and debris so the belt glides smoothly; the low-friction ball bearings are built for years of use.
- Check fasteners periodically and keep the machine on a level surface, ideally on rubber gym flooring.
- No lubricating a motor belt, no motor to service, no electronics to fail — the maintenance a motorised treadmill demands largely disappears.
Combined with a heavy-duty ~175 kg commercial frame, this is why a quality curved treadmill can absorb years of daily commercial sprinting and keep running smoothly — and why, over its life, it often costs less to own than a motorised machine despite a higher sticker price. ATE stocks spare parts and provides pan-India installation and service, so keeping one running is straightforward.
Why buy your curved treadmill from ATE
A curved treadmill is a high-use, high-abuse machine that has to stay smooth and stable under relentless sprinting — so build quality (the frame, the slats, the bearings) is everything. ATE is a fourth-generation Indian manufacturer that builds its curved treadmills in-house to commercial standards, rather than reselling generic imports. That means heavy-duty ~175 kg frames, a choice of cushioned TPE or frictionless aluminium slats, low-friction ball bearings and large, useful consoles — plus a 2-year warranty, local spare parts, and pan-India delivery, installation and service. And because ATE offers the whole range from the best-value C1 to the premium aluminium-slat C1 Pro and X1 Pro, you can match the machine to your space, budget and running feel. Explore the curved treadmill range, the commercial treadmills line, and the wider cardio machines collection.
Add a curved treadmill to your floor
Self-powered, ~30% more calories, instant sprint-to-stop control, better running form, low impact and near-zero maintenance — on a heavy-duty commercial frame with a 2-year warranty. From the best-value C1 to the premium aluminium-slat C1 Pro, made in India.
The rise of the curved treadmill
The curved treadmill isn't new technology — the concept has existed for years — but its move into the mainstream of functional training is recent and accelerating, and it's worth understanding why. For a long time, curved treadmills were premium, specialist machines found mainly in elite performance centres and a handful of hardcore boxes. Two things changed. First, the explosion of functional training — CrossFit, then hybrid fitness, and now Hyrox — created a huge cohort of gyms and athletes whose training is built on running intervals, sprints and conditioning, exactly what the curved treadmill does best. Second, gym owners increasingly value total cost of ownership and durability over headline features, and the motor-free curved treadmill's near-indestructibility and zero running cost became a compelling operational argument.
The result is that curved treadmills have moved from novelty to near-standard in the functional-gym world, and manufacturers — ATE included — now build full ranges to meet the demand. In India specifically, as CrossFit boxes, Hyrox facilities and hybrid studios multiply and buyers become more informed, the curved treadmill is following the same adoption curve, which is why it's increasingly the treadmill you see on a serious functional floor. It's not replacing every treadmill everywhere — motorised machines still serve steady-state cardio well — but on the conditioning floor of a modern functional gym, it's fast becoming the default.
Cost of ownership: why curved can be cheaper long-term
A curved treadmill usually costs more upfront than an entry-level motorised treadmill, and that sticker price is the main hesitation buyers have. But the smarter way to compare is total cost of ownership over the machine's life, and here the curved treadmill often wins. Consider what you're not paying for over the years:
- No electricity. A motorised treadmill draws significant power, especially under heavy commercial use; a bank of them runs up a real bill. A curved treadmill costs nothing to run — for a facility with several, that's meaningful annual saving.
- No motor or board failures. The motor and control board are the most expensive parts to replace on a motorised treadmill, and they're the parts most likely to fail under abuse. A curved treadmill has neither, so the biggest repair costs simply don't exist.
- Far less maintenance and downtime. No motor-belt lubrication, no electronics servicing, minimal upkeep — less staff time, fewer service calls, and less downtime where a machine sits out of action (and out of revenue).
- Longer service life under abuse. Because there's so little to fail, a well-built curved treadmill on a heavy-duty frame keeps running through years of daily sprinting that would wear out a motorised machine.
Add it up over five to ten years of commercial use, and the curved treadmill's higher purchase price is frequently offset — or beaten — by its lower running and repair costs. For a busy functional gym, it's often the more economical choice, not just the better-performing one. That combination of superior training and lower lifetime cost is the quiet reason the trend has staying power.
Where a curved treadmill fits alongside other functional cardio
A functional gym's conditioning zone usually has a few complementary machines, and it helps to see how the curved treadmill fits with them — all of which ATE builds in its athletic endurance and cardio ranges.
- Curved treadmill vs air bike: the air bike is seated, full-body, low-impact and extremely accessible; the curved treadmill is running-specific, weight-bearing and form-building. They're complementary — the bike for all-out full-body intervals and the treadmill for running conditioning and sprint mechanics. Most functional floors want both.
- Curved treadmill vs rower / ski erg: rowers and ski ergs are pulling-based, full-body, low-impact machines; the curved treadmill is the running piece. Together they cover the main modalities Hyrox and CrossFit program — run, row, ski, bike.
- Curved treadmill vs motorised treadmill: covered above — curved for conditioning, sprints and durability; motorised for precise steady pacing and programmed incline. Many gyms keep a few motorised machines for members who want set-speed cardio and a bank of curved treadmills for the functional floor.
The takeaway: the curved treadmill is the running-specific conditioning tool of a modern functional floor — it doesn't replace the bike, rower or ski erg, it completes the set, and it's increasingly the treadmill of choice for the way these gyms train.
Placement, space & getting started
A few practical notes. On space, curved treadmills have a substantial footprint and are heavy (the frame is around 175 kg), so plan a stable spot on level ground, ideally on rubber gym flooring; because there's no power cord, you have complete freedom in where you place them and can line up several without any electrical work. On getting started, hold the side rails for your first few steps while you learn how foot position controls speed — walk forward on the curve to start the belt, move toward the front to speed up, and drift back to slow down. Within a few minutes it becomes second nature. On technique, focus on a tall posture and a light midfoot strike rather than reaching out with the heel; the curve will reward good form and gently discourage bad form. Start with walking and easy running to get the feel, then progress to intervals and sprints as your confidence and conditioning build. Because you control the speed completely, you're always in charge — there's no belt to outrun.
Frequently asked questions
What is a curved treadmill and how does it work?
A curved treadmill is a manual, self-powered running machine with a concave (curved) slat deck and no motor — it needs no electricity. You drive the belt with your own feet: run higher up the front of the curve to go faster, drift back toward the centre to slow down, and stand still to stop. Your foot placement and gravity control the speed entirely, which makes it far more demanding and responsive than a motorised treadmill.
Why are curved treadmills better for functional gyms?
They match how functional gyms train: instant self-paced speed makes them ideal for sprints and HIIT, they burn more calories and engage more muscle, they improve running form, they're gentle on the joints, and — with no motor — they survive relentless daily use with almost no maintenance and no electricity cost. That combination of harder training and bombproof durability is why CrossFit boxes, Hyrox facilities and performance gyms are adopting them fast.
Do curved treadmills burn more calories?
Yes. Because you power the belt yourself instead of a motor doing the work, a curved treadmill typically burns around 25–30% more calories than a motorised treadmill at a similar perceived pace. More of your muscles work harder throughout the stride, so you get more conditioning and calorie burn in the same or less time — a major reason they suit fat-loss and conditioning training.
Do curved treadmills need electricity?
No. A curved treadmill is entirely self-powered — it has no motor and needs no electricity, so it costs nothing to run, produces no motor noise, and can be placed anywhere without wiring. You can add several to a facility with no electrical work and no impact on your power bill, which is one of their biggest practical advantages for gyms.
Are curved treadmills good for running form?
Yes. The curved deck rewards good mechanics: to run efficiently you have to land on your midfoot under your centre of mass and stay tall, so heel-striking and poor posture don't work well. Over time this trains a cleaner, more efficient, lower-impact running technique that carries over to outdoor running and sport — which is why coaches and athletes value them.
Are curved treadmills easier on the joints?
Generally yes. A quality curved treadmill uses a cushioned slat belt — TPE slats on ATE's C1, aluminium slats with low-friction bearings on the Pro models — that absorbs impact and reduces strain on the knees, ankles and connective tissue compared with running on the road or a hard surface. You get intense conditioning with lower impact, which suits athletes and those managing joint concerns (with professional guidance where relevant).
Curved treadmill vs motorised treadmill — which should I buy?
Choose a curved treadmill for functional training, HIIT, sprint work, maximum calorie burn, durability and zero running cost — it's the better tool for intense, athletic conditioning. Choose a motorised treadmill if you mainly want precise steady-state pacing, programmable incline sessions, and the simplest possible experience for beginners who just set a speed and walk. Many facilities have both. ATE makes both curved and commercial motorised treadmills.
Do curved treadmills require maintenance?
Very little. With no motor, motor-control board or drive electronics, the parts that fail on motorised treadmills simply aren't there. Upkeep is basically wiping down sweat, keeping the slats and bearings clean, and checking fasteners — there's no motor belt to lubricate and no electronics to service. On a heavy-duty commercial frame, a quality curved treadmill absorbs years of daily sprinting with minimal maintenance.
Are curved treadmills hard to use?
There's a short learning curve — the self-paced curve feels unfamiliar for the first few minutes as you learn how foot position controls speed — but it clicks quickly for almost everyone. Once you've got it, the instant self-pacing is a huge advantage for intervals. Very deconditioned beginners who just want to walk at a set pace may prefer a motorised treadmill to start with.
How much do ATE curved treadmills cost, and what warranty do they carry?
The ATE Curved Treadmill C1 is ₹1,21,600, and the premium aluminium-slat C1 Pro and X1 Pro are ₹1,68,800 each.
