Most people plateau in the gym because they're doing too much of the wrong things, not too little. Dr. Shannon Ritchey reveals a science-backed 4-part framework (REPS) that prioritizes proper stimulus, recovery, and consistency over exhaustion, showing how training smarter—not harder—builds sustainable strength and body transformation. Training close to muscular failure—not just fatigue—is the most important stimulus for muscle growth; the rest test distinguishes between the two by checking if you can do three more reps after a brief pause.
