- Gaining muscle and getting bigger comes down to 2 things: how many healthy calories we eat each day, and how hard we push ourselves in the gym. Calories are literally defined as energy and we need this energy to be able to allow our body to rebuild, repair, and grow our muscles bigger than they have ever been. Not all calories are created equally however, and to ensure the fastest gains
possible it's necessary to make sure that the breakdown of calories you consume is 30% protein, 50% carbohydrates, and 20% fats.
