Stand next to a support, feet hip-width apart. Hold for balance. Lift one leg, extending it forward. Lower into a squat on the supporting leg, maintaining a straight back and engaged core. Descend as far as comfortable while controlling your balance. Return to starting position, pushing through your heel. Repeat on both legs.
Engage your core for stability. Use the support for balance only as needed. Keep your knee aligned with your toes. Control the movement throughout. Start with higher support and gradually reduce assistance.
