These exercises are a great progression from the Plank. The addition of moving your body while holding the Plank position really hits your upper abs. Do two to three sets of five to eight reps each.
- On all fours, rest your hands on the sliders.
- Keep your core braced while sliding your left hand forward as far as you can while maintaining a flat lower back. Maintain your core stability as you pull your left hand back to the starting position. Then repeat on the other side to complete one rep.
- Do not allow your hips to sag! This is a tough exercise, and you might need to modify it by starting on your knees rather than your feet.
If you want a real challenge, you can do these on a suspension training system like the TRX!
