Hypertrophy Specific Training

Hypertrophy-Specific Training™, or HST™, is a method of training designed to quickly and effectively induce whole body muscle growth. It is based on physiological principles of muscular hypertrophy. These principles were first discovered in the laboratory, and then organized into a method of training that would produce predictable and repeatable hypertrophic effects.



Bryan Haycock, author and founder of the Hypertrophy-Specific Training (HST) method and Hypertrophy-Specific Nutrition (HSN), began lifting weights in 1978. Over the last 35 years he has incorporated his passion for bodybuilding into his education as a physiologist and career as a writer and consultant for the sport supplement industry.
