What ever your goal may be, I advise you to go for one of Nons plans. It's definitely worth every penny. I'm on my second one now. The workouts are tailored for your goal and easy to follow. Your body will change shape within weeks. Not only that but i used to suffer with regular back pain. Since I've started my core and back have strengthened and I'm now without any pain.
The diet plan is detailed with different meals each day of the week so you never get bored.
