Keeping your hips lifted, repeat the rolling motion for 12 to 15 reps. Repeat on the other side, resting for 30 seconds beforehand if needed. That's one set. Do three sets, resting for 30 seconds between sets.

Keeping your right leg straight and your toes facing forward, lunge to the left and lower your hips until your left thigh is parallel to the floor. Bend at the hips and lower the dumbbells so they're on either side of your left calf (A). Return to center. Next, perform a reverse lunge, stepping back with your left leg. Bend at the hips and lower the dumbbells so they're on either side of your right calf (B). Return to start. Do 12 to 15 reps, then repeat, lunging with your right leg. That's one set. Do three sets, resting for 30 seconds between sets.
