Some bodybuilders use drugs such as anabolic steroids and precursor substances such as prohormones to increase muscle hypertrophy. Anabolic steroids cause hypertrophy of both types (I and II) of muscle fibers, likely caused by an increased synthesis of muscle proteins. They also provoke undesired side effects including hepatotoxicity, gynecomastia, acne, the early onset of male pattern baldness and a decline in the body's own testosterone production, which can cause testicular atrophy. Other performance-enhancing substances used by competitive bodybuilders include human growth hormone (HGH), which can cause acromegaly.
If you have little experience of weight training and free weights, you may wish to start with the machine leg press instead of the squat, especially if you're not accompanied by a trainer, helper or spotter. Even so, there is no reason to be intimidated by the squat exercise. It need not be done in a squat rack or power cage with the big bar and free weights to begin with, although squatting with the bar alone is a good way to practice form. Dumbbells or small-bar barbells or a Smith machine can provide reassurance for the beginner. The same applies to the racked bench press with heavy bar, which can be substituted with dumbbells or lighter barbells. The key is not to lift too heavy too soon.
Ever since Arnold Schwarzenegger famously (and colorfully) stated the intense joy of achieving a great pump, bodybuilders have sought it like the holy grail in their training. But make no mistake: The pump is a result of higher-rep training, especially when combined with advanced training techniques that thoroughly exhaust a muscle. That's best left for the end of your workout. The fact is, you don't want to use that style of training to start your body-part training.
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.
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.
Start with moderately heavy weights. Picking the right amount of weight to lift is important to build the right kind of muscle and avoid injuries. First, you need to determine your max-out weight: the heaviest weight that you can lift, at least once. Use a spotter and find out your max. Ideally, beginner bodybuilders should be lifting 70-80 % of that single rep max for 6-10 repetitions of 3-4 sets. This is the optimal set and repetition range for muscle growth.
Choose your favourite cardio exercises like spinning, outdoor biking, running, hill sprints, or swimming, whatever it is, hit it hard. Literally! Experts advise to perform HIIT, high-intensity interval training, to burn fat in a time-efficient manner. A 3-to-1 rest-to-work ratio is effective. It means you can, for example, go hard as you can on a hill sprint for 30 seconds, walk or jog back down the slope for 90 seconds, and repeat four times for an intense 10-minute training session.

Now come on. I really shouldn't even have to tell you this one. But you wouldn't believe how many times I'm talking to somebody and they say that they're cutting right now. What's the problem with that? Nothing... except for the fact that after we're finished talking they whip out a ho-ho or something and start scarfing down their junk like no tomorrow. And then they go and tell me it's their dinner!! What's up with that? Either they can't handle the bodybuilding life, or they really, really need to do some serious research.
As a certified personal trainer in both commercial gyms and private settings since 2002, and as an assistant coach with the de facto gold standard multisport company in Boise, Idaho, Performance High, LLC., I have been afforded much exposure to the many different fitness communities, from bodybuilders to weekend warriors to enduroletes, whose personalities are all as diverse as their fitness goals.
Starting in an upright position (without locking out your knees), contract your quadriceps muscles and slowly lower into a squat position. Once you reach the bottom movement (where your upper legs are just below parallel to the platform), press the sled back to the top without “locking out” and repeat the movement. Make sure to keep your abdominal muscles tight and your lower back planted firmly against the rear padding to avoid a back injury.
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.
