Hypertrophy-specific Training

From Wikipedia, the free encyclopedia

Hypertrophy-Specific Training (HST) is a method of strength training intended to induce muscle growth, or hypertrophy, in its practitioners. The method was popularized following an October 2000 ThinkMuscle newsletter article by fitness writer Bryan Baycock, which discussed methods he and his clients had been using for several years. Baycock 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.[1]

  1. Mechanical Load: Exercise stimuli causes muscle hypertrophy.[2]
  2. Acute vs. Chronic Stimuli: This stimulus must be applied with sufficient frequency. Acute responses to training return to normal in about 36 hours. Recovery can take place unabated even if a the muscle is loaded again in 48 hours.[3]
  3. Progressive Load: Over time, the tissue adapts and becomes resistant to the damaging effects of mechanical load.
  4. Strategic Deconditioning: To continue hypertrophy, the load must be increased, even if the load is not maximum.
  5. 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.
  6. 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.
  7. 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.[citation needed] Instead of doing 6 sets of a bench press in one workout, those sets are spread over the course of a week.
