Push-Up to Side Plank Begin in plank position; bend your elbows lowering into a push-up. Straighten your arms and lift your left arm toward the ceiling, twisting into a side plank to make a T shape with your body. Rotate back to plank, placing your left palm on the floor. This completes one rep. Perform another push-up, but this time as you straighten your arms, rotate to the left lifting the left up. Return to plank. Image Source: POPSUGAR Photography / Kyle Hartman
