Isokinetic exercise is defined as maximum effort under controlled speeds using accommodating variable resistance.


Normally, in order to create controlled speed, very specialized bulky exercise machines costing thousands of dollars are required. These isokinetic machines control the speed of an exercise by fluctuating resistance throughout the entire range of motion of the exercise being performed. Your speed remains consistent despite how much force you exert. 

Conventional Isokinetic Machine

Unlike free weights, weight machines or elastic bands, whose degree of resistance is like a bell curve, Isokinetics forces your muscles to experience a constant level of resistance throughout the entire range of motion. The effort put into the exercise movement is maximal throughout the entire range of motion, training the muscle from start to finish as effectively and efficiently as it can be trained. The result is greater muscular activation, faster muscle fatigue and dramatically shorter workout times.

The T2 Iso-Trainer uses reciprocal Body Fight in conjunction with your timed movement and our patented housing to make Isokinetic exercise possible without bulky, expensive machinery. Isokinetics combined with the T2's groundbreaking On the Fly Intensity & Exercise Changes makes it the most effective way to build and tone muscle, rendering conventional training techniques like free weights and resistance bands primitive by comparison.
