Squat and Dip
The Squat and Dip exercise works your shoulders, triceps, butt and legs.
Your partner leans against the wall and squats holding the ball above her head. Standing in front with your back to her, place your hands on her knees, then squat. Bend your elbows and lower into a depth. Press up and repeat as your partner holds her position. Do 20 reps, switch positions and repeat.
