Thinking about giving a curved treadmill a shot? You’re definitely not alone!
These days, you’ll see curved treadmills popping up everywhere—in CrossFit gyms, training centers, and even some home gyms. They give you a whole new challenge, one that’s way different from the usual treadmills.
But are they right for you?
The first time I stepped onto a curved treadmill, I quickly realized just how challenging it could be.
I considered myself fit, but just a few minutes in, I felt like I was pushing my limits in a way I hadn’t anticipated. But that’s the beauty of these treadmills—they push you, and you feel every step.
Let me walk you through everything I’ve learned about curved treadmills—the good, the bad, and why they’re making waves
What is A Curved Treadmill?
Curved treadmills are a bit different—they’re non-motorized, U-shaped, and move entirely based on your stride. You’re in control the whole time
Unlike traditional treadmills powered by a motor, the curved treadmill is self-propelled. This means that your own strides entirely power the movement of the belt. Each time your foot strikes the belt, it moves the treadmill.
And let me tell you, running on one of these is no walk in the park
The first time I tried a curved treadmill was a while ago.
It was at my gym, and I had seen a few people using it but was too intimidated to try. Everyone seemed to be sprinting like pros, and I figured I’d give it a go when no one was around to watch me struggle.
So, one quiet afternoon, I finally built up the courage and stepped on. At first, it felt weird—unlike a regular treadmill. There was no motor pulling me along; it was all on me.
Once I got the hang of it, I found my rhythm, and it was exhilarating. And wow, it felt different. When I started running, I could tell I was working harder than usual.
My legs were engaged in a way I’d never experienced on a traditional treadmill. The curved surface forced me to maintain proper form, and I quickly realized I was naturally landing on the balls of my feet, just like I would when running outside.
And it’s not just some. Science backs this up.
Research shows that using a curved treadmill requires 25% more effort than a motorized treadmill. You’re not just running but also working your muscles harder because you’re controlling the machine.
What’s more?
Studies also show an increase of 30% in oxygen consumption and 16% in heart rate while using a curved treadmill compared to flat models.
What Makes Curved Treadmills Unique?

The curve forces you to strike the belt in a way that naturally improves your form. You’ll find yourself running more on the balls of your feet, miming how you would run outdoors and may reduce joint impact.
Benefits of Curved Treadmills
Here are some of the main reasons why curved treadmills are gaining popularity:
- More Muscle Activation. As I mentioned, these treadmills activate more muscle groups, particularly in your lower body. Your calves, hamstrings, glutes, and core work hard to move the belt. This increases your energy expenditure and leads to better fitness gains.
- Natural Running Form. Unlike traditional motorized treadmills that dictate your pace, curved treadmills empower you to set your own speed. This helps you maintain a more natural running form like running outside. The U-shape promotes landing on the balls of your feet, which reduces the strain on your joints.
- Burn More Calories. One of the biggest benefits I noticed was the calorie burn. I didn’t have to log crazy miles to get a good workout. A 20-minute session on the curved treadmill left me feeling like I had just finished a much longer run outside. Studies have shown that running on a curved treadmill can burn up to 30% more calories than running on a flat, motorized treadmill.
- Low Impact on Joints. The curve and rubber belt actually absorb some of the impact, which is great for your joints. So if you’re trying to save your knees and hips from the usual wear and tear, curved treadmills can be a solid option.
- No Electricity Needed. Since you’re powering the treadmill yourself, there’s no need for electricity. This means lower energy costs and a machine you can place anywhere in your home without worrying about cords or outlets.
- Perfect for Interval Training. Curved treadmills are perfect for sprint intervals. You can speed up and slow down on a whim without touching a single button. Just like running outside, you control the pace. This makes it ideal for high-intensity workouts.
The Downsides I Didn’t Expect
Curved treadmills aren’t perfect, and there are a few downsides to keep in mind:
- Not Great for Slow Runs. I found it challenging to maintain a long, steady pace on these machines. The constant need to propel myself forward can be exhausting if I try to maintain a slower, consistent pace for a long time. After about 20 minutes, I’d be ready to tap out, which wasn’t ideal for long-distance training. It’s more suited for interval work or shorter, intense sessions.
- They’re Expensive. Another downside is the price. I toyed with getting one for my home gym, but the cost is steep. It’s great to find a gym with one, but owning one might not be in everyone’s budget. With prices ranging from $4,000 to $10,000, it’s definitely an investment—one you’ll want to be sure you’ll use regularly.
- They Take Up Space. These machines are often bulkier than standard treadmills, and you’ll need a good amount of space in your home gym. If you’re limited on space, this might be a dealbreaker.
Proper Technique
It’s not hard to get used to a curved treadmill, but it does take some getting used to. Here are a few tips to keep in mind:
- Posture is key: Keep your head up, shoulders back, and core engaged. Don’t lean forward too much, or you’ll lose control of the belt.
- Position yourself correctly: Standing too far forward will speed up the belt while standing too far back will slow it down. Try to stay in the center of the machine.
- Stay relaxed: It can feel strange at first, but staying relaxed will help you get into a rhythm more easily. If you tense up, it’ll only make the run harder.
How Fast Can You Run On A Curved Treadmill?
One of the key differences between a curved treadmill and a traditional motorized one is how speed works. On a motorized treadmill, you manually set your speed and incline, then start running. But with a curved treadmill, no motor controls your pace—you’re in charge! Your speed is determined by your movement and how you adjust to the curve of the machine.
What’s exciting is that there’s virtually no speed limit on a curved treadmill. You can keep pushing the pace as long as your legs can keep up. Some elite runners have been clocked at speeds of over 24 mph on a curved treadmill.
How To Get Started on A Curved Treadmill
Curved treadmills can feel a bit different from regular treadmills at first, but don’t worry—once you get the hang of it, you’ll love the workout benefits.
Here’s how to start safely and make the most of your experience on a curved treadmill.
Start Slow with a Walk or Gentle Jog
If you’re new to curved treadmills, start with a walk or a slow jog. This gives you time to adjust to the self-propelled motion and feel how the belt moves with your stride. Focus on finding a steady rhythm, and avoid rushing into a faster pace right away.
Keep an Upright, Slightly Forward-Leaning Position
Curved treadmills naturally encourage a forward-leaning posture, which is beneficial for form. However, avoid leaning too far forward, as this can cause you to lose balance or place strain on your lower back. Keep your core engaged, your shoulders relaxed, and lean slightly forward from the ankles—not the waist.
Short, Quick Steps for Efficient Movement
Curved treadmills encourage a shorter, quicker stride that engages more muscles and minimizes impact. Aim for a midfoot or forefoot strike rather than heel-striking. This stride pattern will help you maintain control and reduce impact on your joints.
Control Your Pace by Adjusting Your Position
Unlike a traditional treadmill, there’s no speed button here. On a curved treadmill, you control your pace by moving closer to the front or back of the belt. Moving slightly forward will increase your speed, while moving back slows you down. This design lets you shift pace naturally, making it ideal for intervals or spontaneous bursts of speed.
Gradually Build Up Your Time
Curved treadmills require more effort, so start with shorter sessions and gradually increase your time as your muscles adapt. Beginning with 10-15 minutes and adding 5 minutes each session is a great way to build up strength and endurance safely.
Best Workouts on a Curved Treadmill
These treadmills shine during high-intensity workouts. Here are a couple of my favorite routines:
- Sprint Intervals
Do 20 to 30-second sprints followed by a minute of rest or easy walking. Repeat for 10 to 15 rounds. This type of workout is perfect for maximizing the benefits of the curved treadmill. - Fartlek Runs
Alternate between fast and slow intervals for the duration of your run. For example, run fast for 2 minutes, then jog slowly for 2 minutes. Keep repeating for 20 to 30 minutes.
Curved Treadmill Cost: Is It Worth It?
Curved treadmills are an investment, with prices starting around $4,000 and going up to $10,000. While they offer unique benefits and can last longer than motorized treadmills due to fewer moving parts, they are still expensive.
If you’re unsure about the cost, check if a local gym has one to try before you commit to buying.
