Which combination is most effective for stimulating growth hormone release during a resistance training session?

• A. Large muscle mass exercises with high intensity and volume
• B. Small muscle mass exercises with low intensity and volume
• C. Large muscle mass exercises with low intensity and volume
• D. Small muscle mass exercises with high intensity and volume

Answer: (A)

Growth hormone response to resistance training scales with how much muscle tissue is involved, how hard the work is, and how much total work is done. When you use large muscle groups, you recruit more motor units and create greater mechanical tension and metabolic stress. High intensity ensures you’re calling on high-threshold motor units and generating strong neural drive, which boosts signaling that promotes hormonal release. Higher volume adds cumulative metabolic stress, extending the stimulus that sustains GH secretion throughout the session. Put together, large muscle-mass exercises performed with high intensity and substantial volume produce the strongest acute GH response. Other options either recruit less muscle tissue, don’t reach the same neural and metabolic demands, or combine both, resulting in a smaller GH increase.
