Begin on your hands and knees with your shoulders directly over your wrists and your knees underneath your hips, also known as the quadruped position. Tuck the foam roller behind your left knee, squeezing it slightly to keep it in place.
While keeping your back flat and hips parallel to the floor, with control, press your left heel toward the sky.
This completes one rep.
Perform three sets of 15 reps per side, followed by a 30- to 60-second rest.
