To build extra muscle, you need to eat in excess of what you currently eat, and work out with weights on a regular basis. How much muscle you can gain, how quickly and with what definition is largely determined by your genetics and age. But everyone at almost any age should be able to gain some muscle and strength with weight training. Proper nutrition is a crucial element in the muscle building process.
This period also saw the rise of anabolic steroids in bodybuilding and many other sports. In bodybuilding lore, this is partly attributed to the rise of "mass monsters", beginning with Arnold Schwarzenegger, Sergio Oliva, and Lou Ferrigno in the late 1960s and early 1970s, and continuing through the 1980s with Lee Haney, the 1990s with Dorian Yates, Ronnie Coleman, and Markus Rühl, and up to the present day. Bodybuilders such as Greg Kovacs attained mass and size never seen previously but were not successful at the pro level. Others were renowned for their spectacular development of a particular body part, like Tom Platz or Paul Demayo for their leg muscles. At the time of shooting Pumping Iron, Schwarzenegger (while never admitting to steroid use until long after his retirement) said that "you have to do anything you can to get the advantage in competition". He would later say that he does not regret using anything.
Figure out how to pay the bills. Bodybuilders don't make lots of money, so the idea of becoming a professional bodybuilder is a lot like the idea of become a professional poet or professional painter: it'll take a lot of your heart and soul, but you'll also need to figure out how to take care of the practical details. You've got to support your bodybuilding with some other kind of work to pay the bills.
In the fourth and final week of the program, you’ll train four days in a four-way split that hits each bodypart just once (except for calves and abs, which are each trained twice). Four-day splits are common among experienced lifters because they involve training fewer bodyparts (typically 2–3) per workout, which gives each muscle group ample attention and allows you to train with higher volume. As you’ll see, chest and triceps are paired up, as are back with biceps and quads with hamstrings, each a very common pairing among novice and advanced bodybuilders. Shoulders are trained more or less on their own, and you’ll alternate hitting calves and abs—which respond well to being trained multiple times per week—every other workout. No new exercises are introduced in Week 4 so that you can focus on intensity in your workouts instead of learning new movements.
The bench press or dumbbell bench-press is performed while lying face up on a bench, by pushing a weight away from the chest. This is a compound exercise that also involves the triceps and the front deltoids, also recruits the upper and lower back muscles, and traps. The bench press is the king of all upper body exercises and is one of the most popular chest exercises in the world. It is the final exercise in 'The big 3'.
When lifting it is essential to focus your mind completely on the muscle group you are attempting to work on. This makes sure that you are actually using the target muscle to lift the weight rather than accessory muscles or even momentum. This skill will develop with time, and as you progress in making that mind to muscle connection, your workouts will become much more productive and efficient.
