The squat is performed by squatting down with a weight held across the upper back under neck and standing up straight again. This is a compound exercise that also involves the glutes (buttocks) and, to a lesser extent, the hamstrings, calves, and the lower back. Lifting belts are sometimes used to help support the lower back. The freeweight squat is one of 'The Big Three' powerlifting exercises, along with the deadlift and the bench press.[2]
Consume 10 to 20 grams of high-quality protein within 30 to 60 minutes of a weights session. Research has shown that an intake of 6 to 12 grams of essential amino acids, which is equivalent to 10 to 20 grams of a complete protein, promotes enhanced muscle recovery and rebuilding after a workout. One gram per kilogram body weight (about 0.5 grams/pound) of carbohydrate taken with the protein may assist this anabolic boost. Some trainers call this a protein "shooter." Options that meet these requirements include 17 fluid ounces of flavored low-fat milk; 1 cup fruit salad with 7 ounces of flavored yogurt; or a large glass of nonfat milk with two slices of bread and honey or jam (no butter).

One of the most persistent questions floating around the minds of many aspiring bodybuilders is “What is the best way to train to build muscle?”. The answers are as varied as the numerous pieces of gym equipment that occupy any fitness establishment. There are many choices as to the best exercises to use, how many sets and reps, how many days per week to train and what type of program to follow.

Identify your body type and what you are striving for. If you want to get into competitions, then it is important to know your body’s strengths and to be aware of what judges will be looking for. Look into the federation’s guidelines and attend a competition to see what the competitors look like.[4] This will help you to design an effective training program along with the guidance of your trainer.

You may have heard hardcore lifters talk about things like "leg day," but when it comes to a beginner strength workout that's only a few days a week, a full-body workout is often the way to go (rather than splitting your days up by body part). "Full-body workouts maximize your caloric burn and the muscles worked each session," says Davis. The best way to do this is to pair one upper body exercise with one lower body exercise. "This way, the lower body has time to recover while the upper body works and vice-versa," says Davis. You should also aim for a balance between movements that feel like pulling and ones that feel like pushing. For example, Davis suggests pairing these exercises together:
Weight: Beginners should start with weights that can be lifted 10-12 reps to fatigue with good form. Fatigue means that you cannot lift the weight one more time with good form. If you have to lean back or throw the weight up, then it's too heavy. Lifting 10-12 reps to fatigue will maximize your strength gains and minimize the risk of overtraining or injury.
Shorter rest periods have their place — especially if your goal is muscular endurance and fat loss. But longer rest allows you to perform more reps on subsequent sets, and this greater volume, over time, may lead to greater muscle gains in the long run. One convenient way to do this without tacking additional time onto your bodybuilding routine: Perform supersets, which are back-to-back sets of two different exercises that target non-competing muscle groups (e.g., the squat and biceps curl, or the bench press and bent over row).

Arnold included basic multijoint movements in his routine that hit the pecs from a variety of angles. "I knew the routine had to be basic and very heavy," he wrote. Basic, for Arnold, meant sticking to flat, incline, and decline benches while occasionally training like a powerlifter rather than trying a multitude of machines or using trendy techniques. Arnold saved pumping sets for the end of his workout.

Does this mean that everything is as good as everything else? Of course not. I'm a strength coach, and I believe that a full-body strength program built around compound lifts is the best place for almost everybody to start, no matter what they end up doing months or years later. It's better than so-called fat-loss programs, hypertrophy programs, programs that help add inches to your vertical jump, or ones that promise to turn you into a superhero in eight weeks.
In terms of actual gains, depending on the factors listed above, maybe 12-15 lbs. of muscle, 15 lbs. being on the high end. This assumes you are natural, by the way. Drugs are a personal choice, but my experience is as a natural bodybuilder, so I'm not going to pretend to know a lot about how steroids affect your gains. Having said that, it makes sense to at least be aware of what they are and what they do, purely from a knowledge standpoint. There are enough knowledge resources available on line that you can learn about them if you choose to pursue that option.
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.
