Strength Workout: Scorpion

Add this move to your strength routine to run stronger and faster.

Get into pushup position but with your feet on a bench. Raise your right knee toward your left shoulder as you rotate your hips up and to the left as far as you can. Then reverse directions, rotating your hips up and to the right, and try to touch your right foot to the back of your left shoulder (you won’t be able to do it). That’s one repetition. Continue for 30 seconds with your right leg, then switch legs.

Modifications: To make it easier, do step one of the exercise, twisting in just one direction. To make it harder, instead of putting your feet on a bench, do the exercise with your shins on a stability ball.

Repetitions: As many as you can in 30 seconds

Muscles worked: shoulders, core
