TRISOmetrics™ is an advanced, high-intensity science-based exercise system which combines 3 proven exercise techniques into one powerful system. The TRISOmetric™ exercise system will deliver maximum strength gains and muscle growth in minimum time. Multi-angle isometric contractions provide maximum strength gains through a smooth strength curve along the complete range of motion of a limb. Maximum muscle fibre engagement is achieved through super-slow isotonic compound combinations, and rest and recovery time optimisation during each exercise delivers outstanding, powerful results. By focussing on precision quality and high-intensity exercise instead of mediocre quantity means that your workout sessions are kept short in length, infrequent in number, and big on results. TRISOmetric™ exercise techniques can be performed either without any special equipment, with regular gym/resistance equipment, with freehand calisthenics, or with a combination of specific isometric/isotonic equipment. The choice is yours, and often several versions of the same exercise demonstrate this. TRISOmetrics™ can also be used with the amazing Iso-Bow® exerciser, the Bullworker®, the Steel Bow®, the Bow Extension®, the Iso-Gym®. TRISOmetrics™ is part of the ISOfitness™ exercise system which aims to deliver more results, in less time, and with less exercise than any other exercise system.
