Each stride pulls the belt behind you, requiring no electricity. As you increase your pace, the belt responds by moving faster, so how fast you go at any given time is entirely up to you. The shape also makes it very ergonomic – a U-shaped treadmill reduces joint stress and feels natural while keeping your form in line. Run at your own pace, and you can even train harder with the Curve Selector!\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in; line-height: normal;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 class=\"MsoNormal\" style=\"margin-bottom: 0in; line-height: normal;\"\u003e\u003cb\u003eNatural, Self-Powered Running Experience\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in; line-height: normal;\"\u003eUnlike electric treadmills that move the belt for you, this curved manual treadmill runs on your stride.

Curved treadmills burn up to 30 percent more calories. You engage more muscle groups when you move it yourself.   A study of 13 trained runners (see link below) found that using a curved manual treadmill resulted in a heart rate up to 16% higher. They also had a 2.5% higher running cadence (steps per minute).  Want to level up your workout?
