#**[Set Volume for Muscle Size: The Ultimate Evidence Based Bible](https://weightology.net/the-members-area/evidence-based-guides/set-volume-for-muscle-size-the-ultimate-evidence-based-bible/)** James Krieger of Weightology (and recent [BF% post](https://old.reddit.com/r/Fitness/comments/e4fldb/this_is_a_great_series_by_james_krieger_on/)) just released his "Volume Bible" on hypertrophy training. We've probably all heard "[volume drives gains](https://i.imgur.com/7bOp283.jpg)" a lot recently, and here, Dr. Krieger provides a thorough assessment of the evidence to suggest the best way to manipulate volume when training for size. Mike Israetel has stated several times that Krieger's Volume Bible informs Renaissance Periodization's [Hypertrophy Training guidelines](https://renaissanceperiodization.com/hypertrophy-training-guide-central-hub/). It's a beefy write-up to sink your teeth in, but the key takeways and tl;dr are upfront: >**TL;DR Version** >* On average, muscle growth tends to be best with around 8 sets per muscle group per training session in trained individuals. Frequency can be used to manipulate weekly volume. >* Individual results may vary widely from the average. >* 2-3 sets per muscle group per training session is sufficient for beginners. **** Bonus material: If that's not enough nerding out for you, a couple of reviews looking at the the other side of the coin have recently come out too: * [The Minimum Effective Training Dose Required to Increase 1RM Strength in Resistance-Trained Men: A Systematic Review and Meta-Analysis](https://link.springer.com/article/10.1007/s40279-019-01236-0) * [Training for strength and hypertrophy: an evidence-based approach](https://www.sciencedirect.com/science/article/pii/S2468867319300513) **** Happy Brain Gains
