I am all about not reinventing the wheel. This girl is AMAZING! You can get her dvd's or her webcasts and you can get a 7 day free preview. For awhile you could get these free on comcasts ondemand feature or through exercisetv. She was the one go to person I would go to for my work outs. She keeps you energized and motivated without screaming at you.
So if you need some new routines, definitely check out Chris Freytag!
Have a very fit day!
