Targets: Biceps, abs, butt, and legs
Holding a dumbbell in each hand, arms by sides, palms facing forward, stand with back to stability ball, feet hip-width apart.
- Bend both elbows and draw them behind your back so that ends of dumbbells brush either side of hips or come as close to them as possible without straining. Bend right knee and place right shin on top of ball behind you. (MAKE IT EASIER: Rest right shin on a bench or keep both feet on floor for a traditional squat.)
- Sink into a single-leg squat.
