It's been said before, but it's worth repeating: Strength and muscle are made in the gym; physique is made in the kitchen. You can't out-exercise poor nutrition. You can strengthen every muscle you want (and there's nothing wrong with that), but if you want to see all the hard-earned results, the striations and sinew, proper nutrition is a must. Though it may seem like a 50/50 thing where exercise and nutrition play equal parts in fitness, the truth is it's more like 80/20 (nutrition and exercise, respectively).
That 80 percent is really tough to do, but it is doable if you really want it. By just cutting out a few things here and there, or replacing them with something healthier, you can make a big difference inside and outside of your body. We must work the 20 percent to grow from the inside-out, and the 80 percent to shrink from the outside-in. In this way, we meet ourselves in the middle.
