Description

Technical Field

[0001] This utility model relates to the field of stepper technology, specifically a stepper with adjustable resistance. Background Technology

[0002] A stepper is a type of fitness equipment that allows users to repeatedly perform the motion of climbing stairs. This not only enhances the function of the cardiovascular system but also effectively exercises the thigh and calf muscles. The stepper uses pedals that swing up and down alternately to simulate the motion of climbing mountains or walking up stairs, thereby training the leg muscles to achieve health and fitness goals.

[0003] Most steppers use a reciprocating oscillating motion, that is, the left foot steps down and the right foot rises, or the right foot steps down and the left foot rises. Traditional steppers provide resistance through hydraulic cylinders connected to the bottom of the pedals to exercise leg muscles. The resistance level needs to be adjusted by adjusting the pressure inside the hydraulic cylinder or changing the height of the pedals to adjust the intensity of the exercise. Both of these adjustments require disassembling the parts to make adjustments, which is inconvenient. At the same time, the cost of adjusting with hydraulic cylinders is also relatively high, which leads to the high price of steppers. Therefore, further improvements are urgently needed.
