This Study Completely Changed How I Train To Failure
Shownotes
In this episode, I sit down with exercise scientist Dr. Martin Refalo to discuss his research on reps in reserve (RIR) and what it reveals about how close to failure you need to train to maximize muscle growth. We also explore how exercise selection and fatigue influence your training, and whether low-volume training can be effective for building muscle.
