Guest guest Posted December 11, 2006 Report Share Posted December 11, 2006 The extreme version of Matt Kahl's interesting proposal is known as the Prinicple of Reciprocal Inhibition. For example, with a max of about 3 seconds rest between sets of opposing muscles, ie; working bi's and then tri's (agonist/antagonist) illicits a greater increase in strength than traditional BB training of mutliple high rep sets of the same muscle before moving on to a different exercise or muscle group. When my athletes are in a muscle hypertrophy phase, we usually take a 2 min. rest between sets of 8-12 reps for each exercise. Example: 8- 12 reps heavy curls with ez curl bar followed immediately by a set of 8-12 reps heavy skull crushers. This scheme can only be used for a month or two, but utilized with an athlete with a good strength base, always generates major increases in strength and stimulates muscle hypertrophy. Intuitively one would think that the greater intensity of agonist/antagonist training, done synergistically, would stimulate greater hormone release. And although none of my young athletes can afford expensive hormone tests, my experience has been that it is an extremely effective method to grow a bigger, stronger athlete in a relatively short time.
