Hip Abduction - single leg
Start by standing on the top of the Bosu with feet a little than shoulder-width apart. As you contract the core, put all of your body weight on the left leg. Keep a slight bend in the left leg. Slowly lift the right leg by leading with the outside of the foot. Keep your foot flat by pointing your toes forward and not to the sky or to the side. Once your right leg is lifted, slowly lower the leg to the Bosu. Once your foot touches the Bosu, repeat the movement with the same leg until the set is finished. Keep the core contracted, back flat and eyes facing forward. This exercise should not be completed quickly. Repeat with the other leg.
