The single leg squat strengthens your quadriceps and glutes to facilitate an improved ability to perform functional activities such as standing up from and sitting down in a chair, squatting, and climbing stairs. Increased strength of your lower body muscles also helps to improve balance and decrease your risk of falls.
Begin standing on one foot. Keep your opposite knee bent so that your foot is behind you.
Slowly bend your standing hip and knee, lowering as if you are going to sit down in a chair. Your goal should be to bend your knee to almost 90 degrees. Then return back up to the starting position.
