A little more muscle goes a long way, especially as you become leaner. That’s why this workout focuses on the big stuff: big muscles, big weights, big calorie burn, big payoff. It all helps you add serious size to your chest, back, legs, and arms, while finishing off the flab that covers your abs. Use this routine for 4 weeks and you’ll be on your way to looking as fit as an action star.
