Abstract
The exercise machine with a variable resistance system includes a frame, an exercise implement movably connected to the frame, a main shaft rotatably connected to the frame, a main connector attached between the main shaft and the exercise implement, a plurality of resistance assemblies and a plurality of actuation assemblies adapted for selectively engaging or disengaging at least one of the plurality of resistance assemblies with respect to the main shaft. The plurality of resistance assemblies apply a total level of rotational resistance against the main shaft based on which of the plurality of resistance assemblies are engaged with the main shaft by the plurality of actuation assemblies.
