Ab Knee Ups

Ab knee ups are great exercises for hitting the entire abdominal region. A fairly simple exercise to do that can be done anywhere. You can do this exercise on a bench or the floor.

This exercise is all about contraction so really concentrate on flexing those abs throughout the entire movement. If your just beginning, you don't have to go all the way up to your chest, try and come up as far as you can and go back down. Remember, don't let your feet hit the ground.

Position for the ab knee up

1. Sit on the edge of a flat bench and place your hands behind your buttocks. Lean back until your body is at a 45 degree angle.

2. Extend your legs until they are almost straight.
