The Stability Ball Flab-Fighting Workout

Butt Burner

Targets butt, hamstrings

• Stand facing a wall with feet hipwidth apart. Bend left knee behind you with foot flexed and place ball between calf and butt; place hands on wall. MAKE IT EASIER: If ball feels too big to stay put, squeeze a rolled-up towel behind your knee.
• Press left foot up 1 to 2 inches toward ceiling while squeezing ball with leg.
• Do 20 to 25 reps, switch sides and repeat. Do 3 sets.
