Advanced Weighted Cable Crunch

Training with resistance can help add thickness to your abdominal muscles, creating deeper cuts. To create a more effective, cable crunch, kneel on a bench with your feet anchored by a dumbbell. The bench will allow you to go lower at the bottom of the movement, created a greater squeeze. So, stretch up at the top, squeeze low at the bottom.
