Abstract
An exercise apparatus includes a resistance system which has a first rotating shaft, a second rotating shaft and a transmission mechanism mounted between the two rotating shafts, such that the two rotating shafts are rotated with respect to each other at a predetermined transmission ratio. Besides, a first resistance device is controlled to apply a first resistance against rotation of the first rotating shaft, and a second resistance device is controlled to apply a second resistance against rotation of the second rotating shaft. The first resistance device and the second resistance device can be controlled independently. When a user uses the exercise apparatus to perform exercise, a moving member is driven by movement of the user. When the moving member is moved, the two rotating shafts are driven to rotate simultaneously, namely the user has to overcome the rotational resistance of the two rotating shaft during exercise.
