There are some major key parts to a successful body building routine. I will go over a routine that was created by a personal trainer for me, and it worked wonderfully.

The first thing is to remember that in order to build muscle, your body needs to feed your muscles. In order to gain muscle weight one must (only if he/she is working out) eat 1 gram of protein to 1 kilogram of body weight each day in order to have efficient muscle growth. Diet is essentially the most important part of body building. When trying to gain weight in muscle mass one should eat every 2-3 hours, or 6 small meals a day. Each meal should contain a serving of protein. Most meat the size of the palm of your hand has around 15 - 25 grams of protein in it. Along with the protein, lots of carbs and a good multi vitamin should be taken.

Second thing is to get a simple routine and stick to it. It is best to split your workout into 2 days.

Day one - For your chest and triceps do 3 sets of dumbell Press, 3 sets of incline dumbell press (or bench press) and 3 sets of dips. For your back and biceps do 3 sets of chin ups, 3 sets of one arm row, 2 sets of reverse flys, and 2 sets of bicep curls. This should only take an hour or 2.

Day two - For your legs, lower back and abs do 4 sets of squats, 4 sets of lunges, 2 sets of hamstring curls, 2 sets of calf raises, 4 sets of sit-ups, and 2 sets of lower back raises(done on a exercises ball). This should only take an hour or 2.

Rotate this 5 - 6 days a week.

For the first 2 weeks of your work out each set should consist of 15 reps. If you cant do 3 sets of 15 reps with the weight you've chosen, then use a lighter weight. If you can
