Running planks

(2–3 times a week)

Get into “up” push-up position. Slowly bring your right knee toward your left arm, twisting from your core (not your shoulders or hips), then return to the starting position; repeat on the opposite side to complete 1 rep.

Do 1–2 sets of 8 reps. To make the move more challenging, increase the number of reps, slow down, or do the move with your hands on a stability ball.
