Greg was recently on the Data Driven Strength podcast to chat about their meta-regression on proximity to failure and hypertrophy. In the episode, Greg, Zac, and Josh discuss what we know about the mechanisms underpinning muscle growth and the weaknesses of the "effective reps" model. We think it's a conversation worth sharing, so we're re-releasing it in our feeds today as a special bonus episode.
