The exercise order should be maintained as above, busy gyms notwithstanding. This order has been designed with large muscle group, compound exercises first, the smaller muscle isolation exercises following and with alternating ‘push’ and ‘pull’ to achieve a session that alternates muscle groups and modes of action as much as possible to enable maximum rest and recovery of the various muscle groups. Some compromises were required. Don’t get too hung-up if you can’t achieve this sequence. It’s not always possible to access equipment when you want it in gyms. In the scheme of things, it’s not fatal.
Your legs are even more important if you play sports. Strong legs will help you run faster, become stronger, and most importantly, lower your chance of being injured. I know this first hand. I used to train my legs sparingly because the workouts were so hard. I simply didn't feel like going to the gym on leg days and even if I did, I would just go through the motions and never train at a high enough intensity.
Weight trainers don’t usually expend the amount of energy in training that endurance athletes do, so they don't have to be as acutely aware of the intake of carbohydrate required to fuel such effort. For example, a marathoner or triathlete may require 7 to 10 grams of carbohydrate per kilogram body weight per day (3 to 5 grams per pound). This is a lot of carbohydrates—equivalent to more than 32 slices of bread for a 150-pound athlete.
Site enhancement oil, often called "santol" or "synthol" (no relation to the Synthol mouthwash brand), refers to oils injected into muscles to increase the size or change the shape. Some bodybuilders, particularly at the professional level, inject their muscles with such mixtures to mimic the appearance of developed muscle where it may otherwise be disproportionate or lagging.[54] This is known as "fluffing".[55][56] Synthol is 85% oil, 7.5% lidocaine, and 7.5% alcohol.[55] It is not restricted, and many brands are available on the Internet.[57] The use of injected oil to enhance muscle appearance is common among bodybuilders,[58][59] despite the fact that synthol can cause pulmonary embolisms, nerve damage, infections, sclerosing lipogranuloma,[60] stroke,[55] and the formation of oil-filled granulomas, cysts or ulcers in the muscle.[59][61][62] Rare cases might require surgical intervention to avoid further damage to the muscle and/or to prevent loss of life.[63]
Attend local competitions. When you are just starting out, visiting local competitions will be helpful for a few reasons: you will be able to get a feel for competitions and what will be expected of you, you will be exposed to your potential competitors, and you will be able to speak with like-minded men and women who also enjoy the sport. You can make connections at a competition you might not be able to make at your local gym.

“The stimulus to put on muscle that won’t be beneficial for running is much higher than people realize, and unless you’re either lifting relatively heavy and frequently and/or eating a hyper caloric diet, you’re unlikely to put on muscle,” says Joe Holder, USATF-certified running coach, Nike+ Run Club coach in New York City. “Just think about strength training one to two times a week, focusing on compound movement patterns, such as a lunge or squat, and shoring up the areas that could lead to increased injury if they are weak, like the hips.”

Competing in a bodybuilding contest can be a source of immense physiological and emotional stress. As one of the most demanding activities one can engage in, it requires extreme control, discipline, and motivation to even be competitive in the sport. To recover from this stress and bring the body back into balance, attention to proper nutrition and supplementation is critical.
Carbohydrates play an important role for bodybuilders. They give the body energy to deal with the rigors of training and recovery. Carbohydrates also promote secretion of insulin, a hormone enabling cells to get the glucose they need. Insulin also carries amino acids into cells and promotes protein synthesis.[26] Insulin has steroid-like effects in terms of muscle gains.[27] It is impossible to promote protein synthesis without the existence of insulin, which means that without ingesting carbohydrates or protein—which also induces the release of insulin—it is impossible to add muscle mass.[28] Bodybuilders seek out low-glycemic polysaccharides and other slowly digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat. However, bodybuilders frequently do ingest some quickly digesting sugars (often in form of pure dextrose or maltodextrin) just before, during, and/or just after a workout. This may help to replenish glycogen stored within the muscle, and to stimulate muscle protein synthesis.[29]
