BIOTRON™ Dynamic Resistance Strength Training or single positive isotonic resistance training is the BIOTRON™ standard dynamic strength training protocol, providing highly effective, weight-like resistance. Without inertia and negative phase resistance, it is safe, low impact with greatly reduced DOMS (Delayed Onset Muscle Soreness. see Safety section) and ideal for anyone with old injuries.

Absent the muscle shortening and micro- tears of the negative phase of training, antidotal evidence supports expectations that this strength training protocol results in noticeably greater range of motion than weight mass training.
