The fastest way to build muscle is by training hard (but not too hard), eating right and a lot and not giving up. The key to muscle building success is having the right plan. If you take the wrong approach you are just setting yourself up for failure.

One of the most important parts of a muscle building plan is diet. Without the right foods and the right amounts of food you won't grow. You need a lot of calories to build muscle. The body needs a lot of protein to build muscle, so you will need to eat lots of protein rich foods. Do not neglect carbohydrates though. Your body needs them for fuel during workouts.

You should be working out 3 to 4 times a week, not more. Do not work out for more than 1 hour at a time. If you keep working out for longer than that you will risk over-training, which will negatively impact your results. Your reps range should be around 4 -12. When lifting form is very important. You should lower the weights slowly and lift them up quickly. Between sets you should rest about 2 minutes. Do not train more than 2 muscle groups at once.

Besides the eating right and working out another key factor is attitude. Do not expect results overnight. It takes time to transform your body. Do not give up if you do not see results after a week. Just keep working out and eating right and you WILL see results sooner or later.
