Abstract: Exercise equipment provides maximum effort repetitions, every rep, safely, through constant velocity. With constant velocity resistance, every person using the equipment can achieve maximum resistance for each repetition, whether their strength maxes out at 5 lbs. or 500 lbs. of resistance. The constant velocity resistance allows for reduced resistance with each repetition as fatigue sets in, without changing the equipment settings. The exercise equipment includes a line coupled to a handle, and retracted by a retraction assembly. An impeder provides resistance for pushing/pulling (depending on the exercise) based on constant rotational velocity of the impeder, rather than resisting with a force of gravity, spring force, or friction. The impeder prevents extraction of the line faster than the constant rotational velocity. Thus, a user can push/pull as hard as desired, and the line can only be extracted as limited by the velocity of the impeder.
