This 16-week plan is built to add up to 16 pounds of lean muscle through structured nutrition and progressive strength training. Using a 4-day split focused on squat, bench, and deadlift, the program cycles through hypertrophy, strength, and power phases to maximize growth. Combined with a lean bulk diet at ~3,100–3,300 calories per day, it delivers steady muscle gain, stronger lifts, and a leaner physique with minimal fat.
