Perform this exercise without your prosthetic on.
Stand with your feet hip-width apart.
Hold a dumbbell vertically in front of your chest, with your hand holding the uppermost end of the dumbbell as if you were holding a goblet with your residual limb supporting it.
Your elbows should be pointing down towards the floor.
Step backward with one leg and squat down bending at the hips, knees, and ankles until your front thigh is parallel to the floor.
Maintain your front knee in line with your toes and do not allow the heel of your front leg to rise off the floor.
Keep your body upright throughout the movement with your head up and your gaze forward.
Stand by pushing through your front leg hip and return to the starting position.
Take time to regain your balance after each repetition.
Repeat with your other leg.
