This workout contains 3 exercises.
1 - Crossover Ab Crunch
Ab Killer!
Exercise Steps
 | Lie on your back with your knees up and your feet on the floot. Cross your left leg over your right leg. Your left ankle should rest just below your right knee, making a triangle between your legs. Put your right hand behind your head, with your right elbow extended to the side. Rest your head and album on the floor. Place your left hand on your right obliques or at your left side. |
 | Now, contract your abdominal muscles to pull your upper body up so your right elbow touches your left knee. Lower, and repeat. After you finish, do the exercise over with the opposite side. |
2 - The 'T'
Challenge your abs in different directions.
Exercise Steps
 | Start with arms spread out to either side and legs straight up in the air. |
 | Drop legs to 45 degrees to the left. Bring back to starting and drop to the right side. Repeat until you can't do anymore. |
3 - Side Bridge
Lie on your side with your forearm on the floor under your shoulder to prop you up, and your feet stacked. Contract your core and press your forearm against the floor to raise your hips until your body is straight from ankles to shoulders. Hold for 15 to 45 seconds, then repeat on the other side. Contract your abs and butt muscles forcefully to keep your body straight.
