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

  • Most fitness professionals recommend 10-15 sets per muscle group weekly, however, studies indicate benefits of up to 45 sets weekly for muscle growth, especially in highly trained individuals.
  • High-volume training shows a positive correlation with muscle hypertrophy but limited or no benefits for strength gains, indicating a potential dose-response relationship dependent on volume.
  • Different training studies, such as those by Radaelli et al. (2015) and Schoenfeld et al. (2018), demonstrate significant muscle gains with very high volumes performed to failure, particularly for advanced athletes.
  • Psychological factors and training experience significantly impact training results; untrained or less experienced individuals show fewer benefits from extremely high volumes compared to advanced trainees.
  • Meta-analysis of training volume studies suggests that optimal training volumes may vary with training status, with advanced trainees benefiting from higher volumes.
  • Exceedingly high training volumes may lead to issues like reduced willpower, increased risk of injury, and potential overtraining, underscoring the importance of personalized training volumes based on individual recovery capacity and other factors.
  • Nutritional support plays a crucial role in recovery and adaptation to training volumes, with adjustments necessary during periods like fasting or different nutrition phases (bulking or cutting).
  • Conclusively, while extreme training volumes can maximize muscle gains in well-conditioned athletes, it is critical to balance training load with recovery, nutrition, and individual capabilities to avoid negative outcomes.

Peaking – AKA how to hit PRs in meets

How many times have you heard someone say something like: “Well, I squatted 500 in the gym a few weeks ago, but 450 felt heavy at the meet, and I missed 475.” That’s because they peaked wrong. I’m even convinced that if you ONLY hit your gym PRs in meets, you peaked poorly. If you’re good at progr…

The Belt Bible

Whether or not to use a lifting belt is a highly contentious subject. What effects do belts actually have, and who should (and shouldn’t) use them?

PubMed Doesn’t Replace A Strength Coach

What’s worse than someone who thinks science is worthless? Someone who thinks it’s the best thing since sliced bread, but doesn’t understand it (including its limitations) whatsoever. This post will NOT be as dry as the last one, so feel free to keep reading even if you aren’t a huge nerd. PubMed…
