If you're short on time but still want to build muscle, exercise scientist Mike Israetel shares a simple approach: four 30-minute workouts, adding up to just two hours total in the gym each week.
With a Ph.D. in sports physiology, Israetel specializes in hypertrophy training and helps everyday lifters maximize muscle growth efficiently through Renaissance Periodization, his training platform.
This two hour weekly workout approach is built on principles that maximize efficiency with minimal setup and warmup. It prioritizes cable, dumbbell, and bodyweight exercises over heavy lifts. It also focuses on moderate loads in the 10 to 20 rep range, unrelated muscle supersets, and short rest periods between sets.
