technical field

The utility model relates to a sports device, in particular to a stepper.

Background technique

A stepper is a piece of exercise equipment that increases your heart rate, burns calories, and improves heart muscle endurance.

In the traditional stepper design, the user stands on two pedals with predetermined resistance, and the two pedals are lifted alternately by applying force with both feet. The movement of the steps is like continuously going up the stairs, thereby exercising the muscles of the legs and buttocks. Compared with treadmills, steppers have less impact on the legs, but care must be taken when using them to avoid knee injuries.
