<p>The invention is a portable exercise device which creates a controlled and infinitely variable resistance profile. The exercise device, creates this infinitely variable resistance using springs or elastic bands to create the input resistance versus the use of a weight stack as normally used in most exercise equipment. The advantage of this device over conventional exercise devices is that usage of this resistance medium creates a portable exercise device that can create an infinitely variable resistance profile. The exercise devise may be used while traveling and/or in the home. The ease with which the input resistance elements, such as elastic bands or springs, may be changed makes this device much more versatile for exercising a wider range of muscle groups while using one portable machine.</p> |
