Science of Muscle Growth, Increasing Strength & Muscular Recovery

About this video

Huberman explains the science of muscle growth, strength, and recovery. In the middle slice, Huberman advises that most training sets should not be taken to failure, because, he argues, that allows more total volume without fatiguing the nervous system or depleting the nerve-to-muscle connection. He describes a scientifically supported range in his account of anywhere from 5 to 15 sets of resistance exercise per week per muscle, working at 30% to 80% of one-repetition maximum, with the lower end offsetting strength decline and the upper end increasing strength. Huberman explains that people who can generate hard contractions through strong nerve-to-muscle recruitment, via what he calls Henneman’s size principle, actually need fewer sets, while muscles that are hard to contract need more sets to stimulate growth. He adds that weekly sets can be split across sessions or done in one session, with, he says, the data showing it largely does not matter.

Key takeaways

• Huberman advises keeping most resistance sets short of failure to protect total volume.
• Huberman describes 5 to 15 sets per muscle per week as a supported range in his account.
• Huberman explains that stronger mind-muscle recruitment means fewer sets are needed.
• Huberman says weekly sets can be split across sessions without much difference.
• Huberman frames strength as a nerve-to-muscle phenomenon, not muscle alone.
