Difficulty: Moderately Challenging
Step1
Place the bosu ball flat side down and set up in a clear space in front of the half-ball. Stand with both feet on the bubble of the ball and gain your balance. Then raise your hands out in front of you so they stay at about shoulder height.
Step2
Drop your hips back as if you're sitting down in a chair, keeping your back as vertical as possible. As you descend through the down phase of the squat try to make your knees track over your toes so they don't fall inward (towards each other) or kink outward.
Step3
Descend through the down phase of the bosu ball squat to the lowest position that your flexibility and balance allow. If you can get into a full squat with your butt an inch or so off the ground you should do so. Once you've descended to your lowest position, drive through your heels to stand back up, keeping your back tight and as straight as possible as you do so.
Step4
Add weight to the exercise by holding a dumbbell in each hand and then extending your arms out in front of you to shoulder length. The added weight will increase the challenge level and the payoff of the exercise greatly.
