Ab Twist
Lay on your back and lift your legs above your body, with your feet flat toward the ceiling. Spread your arms out. Slowly lower your legs to the right without touching the ground, and lift them back up. Utilize the oblique muscles to lead this motion. Repeat on the left.
Do 10 reps to each side.
Hip Extension
Lay on your back with your heels about at the tip of your fingers when you reach towards your feet. Tighten your core and lift your hips up until you get to a flat back. Slowly lower and repeat.
Do 15 reps.
Superman
