If you work out hard, good fitness nutrition is essential. The more hours you spend training, the more crucial it becomes that you get your fitness nutrition right.

There are several reasons for that. First and foremost, good fitness nutrition will allow you to get the most from your workouts. That means eating the right thing before, during (if necessary) and after your workouts.

The difference can be enormous - working out hard and then eating junk makes as much sense as buying a Ferrari and then putting farm yard diesel in it. To maximize the effects of your workouts, whether your goal is adding muscle or getting faster, it is essential that you pay attention to what, and when you eat.

There are plenty of books on the market - some are general texts that deal with the issues that affect all athletes, while others deal with specific sports - body building or running for example.

Take your time to figure out the book that's right for you. While some take an approach that emphasizes natural foods, others will steer you more in the direction of supplements. Which is right for you will depend on your preferences and your lifestyle.
