Stand on the Bosu with your feet shoulder width apart. Slowly lower your body by bending the knees. All body weight should be placed on the soles of the feet. Contract the core and keep your eyes forward. Either keep your hands by your side or reach your arms in front of you (wherever you feel most stable). Inhale as you lower your bottom towards the Bosu and exhale as you slowly straighten your legs to return to starting position. Be sure not to put your body weight on your toes and keep your weight even on your feet.
