Curved treadmills are great for High-Intensity Interval Training (HIIT). You’ll increase your heart rate faster and keep it up, thus increasing your need for oxygen and helping torch more calories than regular aerobic exercise. In fact, it is believed that you can burn 30% more calories with this treadmill.
In addition, curved treadmills engage more muscle groups because one’s glutes and hamstrings are all involved in moving the machine.
These treadmills are heavy and sturdy, hence suitable for both commercial use and home use.
