Although muscle stimulation occurs in the gym (or home gym) when lifting weights, muscle growth occurs afterward during rest periods. Without adequate rest and sleep (6 to 8 hours), muscles do not have an opportunity to recover and grow.[citation needed] Additionally, many athletes find that a daytime nap further increases their body's ability to recover from training and build muscles. Some bodybuilders add a massage at the end of each workout to their routine as a method of recovering.[50]
Processed and fried foods will be going bye-bye as part of your bodybuilding program. You'll need five or six small meals each day with lean protein to repair muscles, carbs to fuel your workouts and healthy fats to satisfy hunger. Lebo advises that you create meal plans for your week. Rest your muscles a full 48 hours before working the same muscle group and get plenty of sleep.
General nutrition: Experts advise sticking with healthy, nutrient-rich foods as part of a weight-gaining diet (rather than loading up on caloric, but not nutritious, foods such as candy, chips, and soda). They may also suggest eating five or six smaller meals a day rather than three larger ones. All of this is similar to the advice for the bulking phase of the bodybuilding diet.
Some bodybuilders use drugs such as anabolic steroids and precursor substances such as prohormones to increase muscle hypertrophy. Anabolic steroids cause hypertrophy of both types (I and II) of muscle fibers, likely caused by an increased synthesis of muscle proteins. They also provoke undesired side effects including hepatotoxicity, gynecomastia, acne, the early onset of male pattern baldness and a decline in the body's own testosterone production, which can cause testicular atrophy.[42][43][44] Other performance-enhancing substances used by competitive bodybuilders include human growth hormone (HGH), which can cause acromegaly.
In his phenomenal book "The Power of Habit: Why We Do What We Do In Life and Business," Charles Duhigg dedicates an entire chapter to what he labels the "habit loop." Without giving away any spoilers—I'm not kidding, it's a book that will melt your brain, and you should read it—Duhigg explains that one of the most fail-proof ways to create a habit is to preface the behavior you want to reinforce with a cue.

Train four to five times per week. Although you might be tempted to train seven days a week, or even multiple times per day, this will actually slow down your progress and damage your muscles. Aim for four to five training times per week, varying the types of exercises you do. The human body is highly adaptable, so keeping your muscles guessing is a key aspect of bodybuilding and weightlifting.
Long before he was paid $25 million for his movie roles, Arnold Schwarzenegger penned monthly articles for bodybuilding godfather Joe Weider's muscle magazines. Arnold's writing didn't win any journalism awards, but he later collected his ideas and training philosophies in his best-selling "The New Encyclopedia of Bodybuilding," which is still used as a reference tool by bodybuilders today.
After session 12, consider whether you need to increase the weight for any particular exercise. If you can comfortably do more than the RM of 12 exercises, increase the weight by a modest amount, say two pounds or a kilogram for isolation exercise muscles such as triceps and biceps, and 5 pounds or 2.5.kilograms for compound and large muscle group exercises like squats and deadlifts. When using dumbbells, this would apply to each one. Don’t increase the number of sets beyond 3 at this time.
