30 Seconds Summary
How close to failure should you train?

  • Training close to failure (between 5 to 30 reps per set) is generally effective for muscle growth, debunking the traditional 6-12 rep hypertrophy zone.
  • The Effective Reps Model suggests the last five reps of a set (to failure) are the only ones that count towards muscle growth.
  • Critiques of the Effective Reps Model argue it lacks supportive evidence, suggesting the model oversimplifies muscle fiber recruitment and does not align with broader research findings.
  • Recent meta-analyses show contradictory results on the necessity of training to failure, with some suggesting it benefits muscle growth by increasing volume (reps) and others indicating limited or no additional benefits.
  • For strength training, proximity to failure is less crucial than maintaining explosive movements and high muscle activation without complete failure to avoid neuromuscular fatigue.
  • Current analyses conclude that volume (total reps) matters more than simply training to failure; strategies vary between prioritizing time efficiency (fewer sets to failure) and reducing fatigue (more sets, less failure).

Can We Predict Muscle Growth?

Are any of the ways we can measure training volume actually causative (or at least strongly predictive) of muscle growth?

The Evidence is Lacking for “Effective Reps”

The idea that the last 5 reps before failure are “effective reps” doesn’t actually have much all that experimental support.
