Stand with feet hip-width apart with your weight in the middle of your feet and your torso in a neutral position.
Bend your knees, keeping your weight in the middle of your feet until your thighs are parallel with the floor and your knees are over your feet in a squat position. Shift your weight to one foot.
Press the foot into the floor to activate the buttock and thigh muscles. Gently bounce up and down in this position for a few seconds. Then shift your weight to the other side and repeat with the other foot.
