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.
In either phase, don’t exceed 1 gram per pound of body weight of protein (2.2 grams/kilogram). A little more probably won’t hurt a healthy person, but chances are, based on the science of protein requirements for athletes, it won’t help either. It will only cost you in expensive supplements or food. Any hint of kidney disease and you would need to be cautious about excessive protein intake. Consult your doctor for advice if this applies.

You can use your own body weight for resistance exercise. Pushups, sit-ups, chin-ups, squat thrusts, lunges, and step-ups are just some of the exercises that you can do to strengthen your body. The advantage of these exercises is that you can do most of them anywhere, and even though you can't change your body weight to increase or decrease the resistance, there are some things you can do to increase the resistance. Here are some suggestions.
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.
Resistance exercise doesn't mean resistance to exercise! Instead, it's a type of exercise that has gained popularity over the last decade or so as researchers discover the many benefits it has to offer. It's so mainstream at this point that the American College of Sports Medicine, the governing body for exercise in the United States, has included it in its recommendations for all Americans since 1998. In this article, all that you need to know about resistance exercise will be presented: what it is, how it works, how to prevent injury, some of the most popular resistance exercises, and a general resistance-exercise plan.
For lat pull downs, I recommend using an underhand grip (meaning your palms will face you) or a neutral grip (palms face each other… this grip is much less stressful on your elbows/wrists). This is because I’m going to recommend an overhand grip (palms face away from you) during the Upper Body B workout. You’ll see. Also, these are to be done in front of your head… never behind the neck.
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.

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.
