You train for a reason. Whether that reason is to increase your strength, improve your endurance, enhance your flexibility, or simply just “to look good naked,” the key to reaching your goal has a lot to do with how you fuel your body. By fuel, I mean food: real, whole, nutrient-dense food. While part of training is for the sheer enjoyment of being active and/or possibly competing, we also want to reap the side effects of a more muscular, lean physique.
