Chin Up Bars for Ab Workouts

You can use your doorway chin up bar for abdominal exercises. Just hang by your hands and raise your knees to waist level. Raise up and go back down slowly as many times as you can. It's tough, but effective. This is another example of the versatility of chin up bars. You can also use ab loops on your chin up bars for an easier and even more effective abdominal workout.
