Q&A: Powerlifting and GLP-1s, and Volume's Effect on Muscle and Strength

Episode Summary

In this episode, Greg answers questions about GLP-1 medications, the effects of getting most of your protein from supplements, soreness, and how higher training volumes could lead to more muscle growth but not larger strength gains.
