For body-builders, the combination of both muscular growth and an ultra-lean body fat percentage will not generally co exist by simply working out all the time. You have to train during periods of leaning and growth, separately. Body-builders reach their signature look of low body fat and enormous muscles through cycles of what's called bulking and cutting.
Bulking is defined as deliberately packing on poundage with the aim of simultaneously stimulating muscular development throughout practice, and then afterward slimming down with larger and more impressive muscle definition. Cutting is the action of reducing down for purposes of having a trimmer physique.
Bulking is the muscle building growth period. In order to bulk, lots of calories are needed. This is called a caloric surplus, and it simply means to get more calories than you are burning. The added calories should go towards building more muscle mass. They provide you with the energy needed to power-through the heavy and hard workouts it requires in order to attain this specific mass. But bulking includes a drawback. Your own body fat percentage increases. No matter how clean your excess calories are, the typical person will accumulate a lot of fat, as that's just the nature of the game.
It's time for the cutting phase as soon as you've grown muscle tissue that's adequate. This is the opposite of bulking. You consume fewer calories than you're burning to create a caloric deficit, and that reveals the underneath muscle. While this still calls for eating, you are keeping your daily protein intake so, that your body does not cannibalize its own muscle, and adding cardio in to the combination, to burn off your own fat.
Ordinarily, an expert stylist will cut for a few months during competition season and then will bulk for 6-9 months. Recreational bodybuilders bulk over winter when they can wear oversized clothes, and then they start cutting in the spring so they look amazing when summer comes around.
You shouldn't be tricked into believing that you can have the best of both worlds, especially when it comes to big muscles and single-digit excess fat. You don't get there by only eating right and training. Abs are shredded along with substantial muscles, and they have opposite requirements. It takes a lot of balance and a great deal of time to attain both. Sometimes even years. Additionally, it takes a well-trained mind to trust the process and see it through, because in any case, results are never instantaneous.
