11. Forward Lunge
Lunges are great for the hips, thighs and butt!
12. Swiss Ball Hip Raise & Leg Curl
Lie face up on the floor with a Swiss ball under your heels. Raise your hips so your body is in a straight line and then bend your legs, bringing your feet closer to your body by rolling the ball along the floor. Pause and then roll back down. Repeat a couple of times if you can—this one is tough!
