How many times have you been asked the best way to develop a six-pack? If you’re like me I always chuckle a little and inform the inquisitor that he or she already has a six-pack – the problem is that it’s usually being stored in a cooler. I go on to inform him or her that core training requires a lot more work than one or two exercises and that I can help them move toward their goals, but it will require some commitment on their part.
