Abstract
An exercise apparatus and method utilizes a flywheel mounted on a rotatable axle. The user exercises by accelerating and decelerating the rotation of the flywheel. For example, a line which wraps around the axle provides a mechanism for accelerating and decelerating the flywheel when a user applies a pulling force to the line. The inertia of the flywheel resists the user applied pulling force and provides the exercise mechanism. Preferably, spool mounted on the axle and variable pivot locations provide a mechanism for easily varying the exercise resistance.

1-54. (Cancelled)
An exercise apparatus comprising:
- a rotatably mounted axle;
- a weighted flywheel communicating with the axle and adapted to rotate with the axle;
- 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 lines 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 and a second muscle group performs a negative work portion 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 changes.

An exercise apparatus, comprising:
- a frame configured to be supported on a substantially flat surface;
- an axle rotatably mounted to the frame;
- a weighted flywheel communicating with the axle and adapted to rotate with the axle;
- a line having first and second ends, a wrapped portion of the line between the first and second ends being wrapped about the axle;
- first and second handles attached to the line on opposite sides of the wrapped portion, the handles adapted to be operated by a user;
- and
- a line guide between each handle and the wrapped portion;
- wherein the apparatus is configured so that a user simultaneously applying force to the first handle with a first muscle group and the second handle with a second muscle group while the axle is rotating simultaneously performs positive work with the first muscle group and negative work with the second muscle group, and such positive and negative work oscillates between the first and second muscle groups as the rotational direction of the axle changes.
