Superman: Better, faster, stronger!
This is the epitome of pain, but it sure is worth it. The Superman move is similar to a plank, except you raise your legs and arms instead. Just don’t get too relieved when your set is over, or you might bump your nose against the floor!
It works out your back and helps build a strong core.
Lay your hands out in front of you. Life up your arms and legs from the ground and hold for a few seconds.
