EP 205: What Works and What Doesn’t When It Comes to Muscle Building; Science and Practical w/ Brad Schoenfeld 

Jun 25, 2025
Brad Schoenfeld, exercise scientist and author known for muscle hypertrophy research, breaks down what truly drives muscle growth and what myths to drop. He covers tension, volume versus intensity, rep-range strategy, training frequency, recovery nuances, and practical tips for beginners through advanced lifters. Short, evidence-forward takeaways with real-world training advice.

ANECDOTE

Thirty Rep Sets Made Subjects Puke

  • Brad's 30-rep study made many subjects vomit in week one due to metabolic acidosis from high-rep sets.
  • He uses that example to warn that high-rep, near-failure work is unpleasant and often requires longer recovery or deloads.
INSIGHT

Hormone Spikes From Short Rests Don't Build Muscle

  • Transient hormonal spikes from short rest intervals do not meaningfully drive hypertrophy.
  • Brad explains short rests raise growth hormone/testosterone transiently, but longer rests (≥90s) are preferable for muscle gains.
ADVICE

Save Time With Antagonist Supersets

  • Use paired antagonist supersets to save time without reducing hypertrophy.
  • Brad's group found similar gains with supersets and a ~40% shorter workout in trained lifters across studied muscle groups.
