terrific exercise

The plank may sound like something really scary and for some it may be a scary exercise, but the plank is one of the best exercises that you can do to strengthen the core muscles of your stomach and back.

The plank is a great exercise to incorporate into your workout routine because, not only will it work out your abdominal muscles, but it will strengthen your entire core (back, hips) which is so important for daily activities that you don't even think about.
