## Abstract

The system provides an exercise device where resistance is provided by one or more of gyroscopic forces, centrifugal forces, magnetic forces, torus forces symmetric field physics, electro-mechanical forces, mass shaping, frequency dynamics, etc. In one embodiment, a handheld device with an internal flywheel is provided. The flywheel is spun up to a desired speed and provides a gyroscopic resistance to movement in a particular direction relative to the orientation of the device. By holding the device in a particular orientation and attempting to move the device against the gyroscopic effect, resistance is provided for exercising. The device itself is relatively light so that the resistance exists principally when the device is being moved. In one embodiment, the rate of rotation of the flywheel can be controlled via an on-board control so that the resistance can be increased or decreased during exercise movement.

## Claims

### Claim 1

A device comprising:
a handheld housing;
a gyroscopic force creating system mounted within the housing for creating gyroscopic force resistant to movement of the handheld housing in at least one direction, wherein the gyroscopic force is greater than the weight of the device;
a controller coupled to the gyroscopic force creating system for modifying the amount of gyroscopic force; and
a processor/memory means coupled to the gyroscopic force creating system for controlling the device pursuant to one of a plurality of programs controlling the amount of force generated by the device and the length of time the force is generated,
wherein the device is configured to generate substantially all of the force when the device is being moved and substantially no force when the device is not being moved.

### Claim 2 (depends on 1)

The device of claim 1 wherein the force creating system is a rotating flywheel.

### Claim 3 (depends on 2)

The device of claim 2 wherein the housing further includes a handle having a power switch located thereon.

### Claim 4 (depends on 3)

The device of claim 3 wherein the housing comprises an upper body portion and a lower body portion.

### Claim 5 (depends on 4)

The device of claim 4 further including a processor/memory unit coupled to the rotating flywheel.
