When you are working on improving your shape nutrition is one of the key success factors. Most nutrients are received from food, though, as I have found out recently, nutritional supplements sometimes are more than necessary. This resource http://bit.ly/Qh9G8S provides a lot of useful information on training, nutrition, supplements and other important things for athletes. I have followed some of their advices about pre-workout meals and proper recovery and my workouts increadibly improved! I see positive results in my endurance and strength. Now I am capable of visiting much more fitness classes than I used to.
