Abstract:
1. An exercise apparatus comprising: a rotatably mounted axle; a weighted flywheel communicating with the axle and adapted to rotate with the axle to provide an inertial resistance; a line having opposing first and second ends that are attached to the axle, a first portion of the line being wound about the axle in a first direction and a second portion of the line being wound about the axle in a second direction; the line arranged so that, for each direction of axle rotation, as one of the first and second portions is unwound from the axle, the other of the first and second portions is simultaneously wound about the axle; and at least one handle communicating with the line and adapted to be operated by a user to manipulate the line to impart oscillating rotational acceleration and deceleration to the axle so that a first muscle group of the user performs a positive work portion against the inertial resistance produced by the rotating weighted flywheel and a second muscle group performs a negative work portion against the inertial resistance produced by the rotating weighted flywheel for each direction of axle rotation, and the positive and negative work aspects of the exercise oscillate between muscle groups each time the rotational direction of the axle and weighted flywheel changes.
