And since you're alternating between two body-weight exercises that work opposing muscle groups, you won't fatigue as quickly as you would if you were working the same muscles the entire time, says Gaddour. (For instance, skier swings to hammer your hips and lower body and a plank to hit your abs.) That means you can go harder and faster for longer.
In order to give you an even bigger post-workout metabolic boost, Gaddour removes the rest from the final 5 minutes of the workout and replaces it with isometric holds. He calls this the body-weight boom.
It'll keep your muscles under tension longer, promoting muscle growth and revving your metabolism for hours after you're done.
