2. Hamstring Balance
Lie on your back with your arms out at your sides for stability. Put both feet on the physio ball. Squeeze your glutes and lift your back off the floor, the goal being to align your torso and legs in a straight line. Next, pick one leg off the ball, keeping it in line with the torso throughout the entire movement. The test is to bend your knee—the leg that is on the ball—and pull your foot in as far as you can, keeping your body off the floor. Then very slowly extend the leg back out, stopping just before you reach full extension. Repeat as many times as you can up to 30 and then complete with the other leg.
