Sports & Fitness

First off, you will not get optimal results without paying attention to both nutrition AND training. But, it really doesn’t matter what type of program you’re on or how hard you train, it will all be in vain if you don’t eat right and provide your body with the right nutrition, or ‘building blocks’.
