I started the P90X fitness program 45 days ago. At half way I can say that it's really worth the sweat of the 10 hours weekly training. Intensive workouts combined with the right food that fuels me up definitively changed within a few months, both my mind and body. Anyway if you want to improve your health and the quality of your life, you should think about such a fitness program, you will think more clearly, feel better under stress and your coordination will improve, let's do it :-)
