These are the manual curved treadmills that though manual are still more expensive than most of the electric treadmills available on the market and in spite of being without any bells and whistles at all. These are also sturdiest of the lot. Looks wise though these are some of the best looking treadmills.

You can say these are actually meant for serious runners or some serious workouts.

Benefits of Using a Curved Manual Treadmill

Set them up Anywhere

No electricity is needed. No noise. Especially in apartments it is very useful.

Safer than Electric Treadmills

The risk of falling down is very less. The treadmill works with the force of your legs and stops when you stop unlike the electric treadmill.

Last longer

The number of moving parts are much less compared to an electric treadmill. They are much more robust too.

You'll Lose Weight

According to the Journal of Science and Medicine in Sport, runners worked 30% more on curved, non-motorised treadmills. In addition, their perceived effort matched the physiological data. 32% more oxygen intake, 16% higher heart rate, and 2.5% higher cadence.

Improved Form & Endurance.

The exertion of keeping the belt moving, regardless of speed, raises your heart rate and VO2 max (your upper limit of oxygen consumption or aerobic capacity).

The arc design encourages you to run on the balls of your feet, resulting in a softer landing and less stress on your joints. “Slightly curved treadmills tend to promote a more upright posture and running stance, with excellent landing mechanics,” says Reid-Simms.

More like Outdoor Running

You manage the pace and consistency of your exercise since they're self-regulating. No more fumbling with controls to find your ideal speed or frantically pressing the stop button because you've gone too fast.

Burns Calories Faster

A curved treadmill, according to its creators, burns 30% more calories. In addition, researchers found that non-motorised curved treadmills had higher physiologic intensity than conventional motorised treadmills. Curved treadmills are ideal for HIIT due to their increased intensity (HIIT). You'll burn more calories and raise your heart rate quicker than a regular aerobic workout. Learn more about the advantages of HIIT and how to perform it in our HIIT guide.

Uses more Muscle Group

Traditional treadmills don't engage your whole leg since you don't have to push to go ahead. On the other hand, curved machines require you to use your legs right away, from your glutes to your hamstrings. As a result, you can't improve your running speed by just training harder.

Running on an arc makes your glutes, hamstrings & calves work much harder than a regular surface. The muscles are engaged for longer and with more focus on the posterior chain.

Less Harmfull for the Joints

Saving your knees doesn't mean giving up jogging. A curved's rubber surface helps cushion pressure on joints and connective tissue, avoiding injuries from hitting the ground. Unfortunately, standard treadmills aren't intended to absorb stress, leaving your joints vulnerable.

One user mentioned, “The curve reduces load on achilles and helped me recover without losing all fitness”.
