When compared to flat, motorized treadmills, curved treadmills offer many advantages for walkers and runners:

It uses more muscle groups

The self-powered nature of curved treadmills makes it similar to walking outside, requiring the user to recruit more from the hamstrings, glutes and core to propel the body forward.

It increases calorie burn

Studies have shown curved treadmills can help you burn about 30% more calories than you would doing the same workout on a flat treadmill.

It improves endurance

Pushing the belt requires more energy expenditure, which in turn elevates your heart rate and improves your VO2 max.

It rewards good form

A curved treadmill requires you to take shorter steps, use your core for power and speed up your cadence to keep the belt moving.

It's easy to use and safe

No buttons or gadgets make hopping on and getting started super simple. Not having to worry about delays in belt speed (it doesn't move if you don't move) also makes it safer.
