PURPOSE of the EXPERIMENT . . . it is the author's contention that the growth of human muscular tissue is related to the intensity of exercise; increases in strength and muscle-mass are rapidly produced by very brief and infrequent training ... if the intensity of exercise is high enough.

It is the author's second contention that increasing the amount of training is neither necessary nor desirable . . . on the contrary, a large amount of high intensity training will actually reduce the production of strength and muscle mass increases.

It is the author's third contention that "negative work" (eccentric contraction) is one of the most important factors involved in exercise performed for the purpose of increasing strength and muscle-mass.

It is the author's fourth contention that nothing in the way of a special diet is required . . . so long as a reasonably well-balanced diet is provided.

It is the author's fifth contention that the use of the so-called "growth drugs" (steroids) is neither necessary nor desirable ... on the contrary, repeated tests with animals and double-blind tests with human subjects have clearly demonstrated that the use of such drugs is strongly contraindicated.

It is the author's sixth contention that maximum-possible increases in strength and muscle-mass can be produced only by the use of full range, rotary form, automatically variable, direct resistance.
