The rules for building muscle have changed. Dr. Jim Stoppani breaks down six science-backed muscle-building rules covering rep ranges, muscle failure, range of motion, rest periods, training volume, and workout frequency.
For years, lifters were told to stay within a specific rep range, keep rest periods short, and train each muscle a certain number of times per week. New muscle-growth research shows there may be more than one effective way to train.
In this video, you’ll learn:
• Why nearly every rep range can build muscle
• How close you should train to muscle failure
• Why the stretched portion of a rep may drive more growth
• How long to rest between sets
• How many weekly sets you may need
• Whether training frequency actually matters
Use these six rules to train smarter, improve your workouts, and keep building muscle without getting trapped by outdated gym advice.
