30 Seconds Summary
16 vs. 24 vs. 32 sets per muscle per week: which is better?

  • Training volume is crucial in fitness regimes, comparable to the importance of energy intake in diet plans.
  • Recent studies show conflicting results on the optimal set range, with some suggesting benefits of high volumes up to 45 sets per muscle group per week, while others indicate deterioration beyond 10 sets.
  • A study by Brigatto et al. (2019) on resistance-trained men compared the effects of 16, 24, and 32 sets per muscle group per week on muscle growth.
  • Participants followed a controlled diet and performed two push and two pull workouts weekly, varying only in the number of sets.
  • Results indicated a trend showing greater muscle growth and strength gains with increased training volume, although not all findings reached statistical significance.
  • Critics of high volume training suggest that increases might just be swelling due to edema, not true muscle growth.
  • The study used short rest intervals (1 minute) between sets, which could undermine potential gains due to neuromuscular fatigue and insufficient muscle tension.
  • Despite significant outcomes, it's advised not to generalize the results as optimal training volumes can vary based on individual recovery capacities and life stressors.

Is there a maximum productive training volume per session?

Training volume and frequency are currently hotly debated. For good reason, as these are fundamentally important considerations for the design of a training program. Over the last year, several studies have reported surprising and seemingly conflicting results. One study says higher training frequen…

The New Approach to Training Volume

The most useful way to think about training volume isn’t sets x reps x weight. There’s a better way, according to new research and practical experience.

New science on the optimal training volume: extreme training for extreme gains?

Most evidence-based fitness professionals recommend a training volume of 10-15 sets per muscle group per week. I’ve recommended 10-30 sets in my interviews the past years for most individuals with some outliers using higher volumes, like IFBB Pro Nina Ross. The truth is, even I may have been overly…
