• Stand with physioball between lower back and wall, holding dumbbells at sides
• Assume stance just wider than shoulder width with toes slightly pointing out
• Slowly push butt back and down to lower into squat position, keeping knees behind toes
• When tops of thighs are parallel to floor, drive into start position

Advanced variation: Perform exercise on one leg

Sets/Reps: 3x12; gradually increase weight

Benefits: This trains double-leg hip, glute and hamstring strength at a slightly different angle than a standard squat. When you change the angle, you change the stress on the muscles.
