Bingeing the night of, or day after the contest is not necessarily detrimental to progress. Unless the competitor is planning to compete again in the very near future, being in a caloric surplus for one to two days is acceptable. Following this period, it is essential to gradually return to patterns of normal, health-conscious eating. Steadily increasing levels of carbohydrates, fats, and proteins can ensure a progressive rise in metabolic rate.
Because the upper traps get some degree of stimulation during many shoulder exercises, Arnold trained them with delts. His main upper-trap exercise was the shrug, though he noted that maximizing the size of this muscle required a number of other movements, including power pulls, cleans, and upright rows. Because the range of motion in a shrug is fairly short, Arnold recommended backing off on the weight in favor of being able to fully shrug your shoulders as high as possible.

The motor proteins actin and myosin generate the forces exerted by contracting muscles. Current recommendations suggest that bodybuilders should consume 25–30% of protein per total calorie intake to further their goal of maintaining and improving their body composition.[30] This is a widely debated topic, with many arguing that 1 gram of protein per pound of body weight per day is ideal, some suggesting that less is sufficient, while others recommending 1.5, 2, or more.[31] It is believed that protein needs to be consumed frequently throughout the day, especially during/after a workout, and before sleep.[32] There is also some debate concerning the best type of protein to take. Chicken, turkey, beef, pork, fish, eggs and dairy foods are high in protein, as are some nuts, seeds, beans, and lentils. Casein or whey are often used to supplement the diet with additional protein. Whey protein is the type of protein contained in many popular brands of protein supplements and is preferred by many bodybuilders because of its high Biological Value (BV) and quick absorption rates. Whey protein also has a bigger effect than casein on insulin levels, triggering about double the amount of insulin release.[33] That effect is somewhat overcome by combining casein and whey. Bodybuilders are usually thought to require protein with a higher BV than that of soy, which is additionally avoided due to its claimed estrogenic properties. Still, some nutrition experts believe that soy, flax seeds and many other plants that contain the weak estrogen-like compounds or phytoestrogens, can be used beneficially, as phytoestrogens compete with estrogens for receptor sites in the male body and can block its actions. This can also include some inhibition of pituitary functions while stimulating the P450 system (the system that eliminates hormones, drugs and metabolic waste product from the body) in the liver to more actively process and excrete excess estrogen.[34][35] Cortisol decreases amino acid uptake by muscle, and inhibits protein synthesis.[36]

This no-holds-barred quest for growth is based on the principle of four: performing four exercises and adding four extra reps to each exercise after the first. Because each lift changes the area of the muscle that receives the most stimuli, the ever-increasing reps shift the demands of the muscle from strength to hypertrophy to endurance to a skin-stretching crescendo that flushes the muscle and celebrates the pump.
The benefits of resistance exercise are well documented, and ongoing research continues to prove that it's an important activity for Americans to be engaged in. Long ago in hunter-gatherer societies, humans' muscles got a workout by building shelter, hunting, farming, and all the other manual chores necessary to live. Today, however, we have engineered inactivity into our lives with labor-saving devices to the extent that our muscles rarely need to be pushed very hard. We don't rake leaves or cut grass or shovel snow by hand; we don't climb stairs or even walk in airports (people movers do it for us!); we don't wash our clothes or our dishes or even push a vacuum by hand (Have you seen the robotic vacuum Roomba?), and we spend more and more time in front of our computers and televisions than we do outdoors raking leaves, playing touch football, baseball, soccer, hiking, or participating in any other recreational activities. Research shows that physical inactivity is the second leading preventable cause of death in the United States, and it's literally killing us.
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.

So, for example, with the moves above you'd do 15 squats followed by 15 push-ups. Take a little breather then repeat that two more times. Then you move on to your walking lunges and lat pull-downs (and repeat those three times total, too). You can really do anywhere from eight reps to 15 (and even just two sets, if you don't have time for three), but "it’s not a bad idea for beginners to start with a 15-rep range to get comfortable with the exercises," says Davis. And while there's some debate over whether three sets of an exercise is really best, "it’s a great beginner model," says Davis. Don't overcomplicate things when you're just getting started.

Perform three weight-training sessions per week, hitting your whole body each time. Base your routine on compound exercises such as squats, lunges and deadlifts. These burn the most calories, hit more muscles and give the best bang for your buck, claims Rachel Cosgrove, strength coach and co-founder of Results Fitness in California. If you're not sure of any exercise techniques, ask a trainer at your gym for assistance.
