The method was popularized following an October 2000 ''ThinkMuscle'' newsletter article by fitness writer [[Bryan Haycock]], which discussed methods he and his clients had been using for several years. Haycock says that the training method arose out of "physiological principles of hypertrophy discovered in the laboratory," and that these principles were then organized into a [[weight training]] method meant to induce hypertrophy.<ref name="hsnaboutus">{{cite web | last = Haycock | first = Bryan | title = HSN: About Us | work = Official Website of HST | publisher = Hypertrophy-Specific Nutrition | date = 2002 | url = http://www.hypertrophy-specific.com/about.html | accessdate = 2008-02-13 }}</ref> ==Principles of HST== {{Primarysources|date=November 2006}} #'''Mechanical Load''': [[physical exercise|Exercise]] stimuli causes muscle hypertrophy.<ref name="ucsdoverview">{{cite web | last = | first = | title = Skeletal Muscle Hypertrophy | work = Muscle Physiology | publisher = University of California, San Diego | date = 2000 | url = http://muscle.ucsd.edu/musintro/hypertrophy.shtml | accessdate = 2006-11-02 }}</ref> #'''Chronic Stimulation''': These stimuli must be applied with sufficient frequency.

This process happens after the end of a 6-8 week "cycle" and can last from 9-14 days preceding a new "cycle". #'''Utilizing lactic acid as a stimulus for tendon repair/health''': Higher reps produce lactic acid which prepares the muscles and tendons for future heavy loads. Compound exercises are used to maximize the effects. #'''Progressively Adjusting reps to accommodate Progressive Load''': HST suggests that you change how many exercise repetitions you perform every 2 weeks, to accommodate the ever increasing load. Most "HST" programs start with a 15 rep, 2 week "semi-cycle" that is performed over six workouts with the sixth workout being at the exercisers maximum weight. The next semi-cycle, reps are reduced to 10, then 5, finally ending with a repeat of the 5 rep cycle, or eccentric repetitions. Each semi-cycle adds to equal one full 8 week cycle. #'''Low volume per exercise (average volume per week)''': HST suggests that you limit the number of sets per exercise per workout to 1 or 2, based on evidence that sets beyond the first set do not contribute to hypertrophy.{{Fact|date=February 2007}} Instead of doing 6 sets of a [[bench press]] in one workout, those sets are spread over the course of a week. ==External links== *[http://www.hypertrophy-specific.info The Home of HST] (Official Site) ==References== <references /> [[Category:Weight training]] [[de:Hypertrophy Specific Training]] [[nl:Hypertrophy Specific Training (HST)]]
