TECHNICAL FIELD

[0001] The present invention relates to the technical field of fitness equipment, and in particular to a treadmill.BACKGROUND

[0002] A running platform of a treadmill is designed with a slope to increase the exercise amount and exercise intensity of a user, and the exercise amount and exercise intensity of the user can be effectively adjusted by adjusting the slope of the running platform, so that the user can adjust the exercise amount and exercise intensity as required. However, a traditional treadmill driven by a motor often consumes a large amount of electricity, generates loud noise and has high cost. The speed of driving the movement is low in a case that other modes are used for driving. In a case that a longer stroke is required for adjustment, longer time is often required, which is difficult to meet the requirement of rapid adjustment by the user.
