How to do it: Get into a traditional press-up position. Lower yourself toward the floor and bring your right knee to your right elbow, keeping it off the ground. Press back up and return your leg to the starting position. Repeat with the alternate leg.
Why: Perfect if you're looking to get some mobility in before a workout or just want to switch up your chest routine, Spiderman press-ups are the perfect alternative if you're looking to scale things up.
