If you are trying to get into weight lifting because you want to build muscle, don't make the mistake of telling some people that you are having problems with trying to gain muscle. More than likely they are going to turn to you and tell you to eat more. Although you do need to eat a lot to be able to gain muscle, eating way too much isn't going to get it done.
A lot of people are going to try and tell you that in order to build those muscles you need to gain weight so the best way that you can do this is eat a lot no matter what it is, pizza, candy bars, steaks, hamburgers you name it, they tell you that's the way to build up that weight gain to increase your muscles. This however is a myth. If you eat everything in sight you'll gain weight alright, but not the kind that you want to gain. So you need to eat a lot of healthy foods not junk foods.
Are you doing far too many repetitions that are considered low with a lot of weight thinking this is going to help you bulk up? If you are, well you can stop right now. The low repetition with high weight as compared to the high repetition with low weight isn't going to make any difference in the size of your muscles. As long as you are simply pushing each set of repetitions to the max for yourself, you will overload the muscles and they are going to grow and get stronger.
A lot of different magazines and DVDs try to lead you to believe that if there is no pain there will be no gain. Just another myth. If you happen to keep pushing yourself as hard as some of those guys in those magazines and recordings of course you are going to get as big as them. Not. These people, at least the ones not taking illegal drugs, are genetically predisposed to being able to carry this kind of muscle weight on their body frames. You also need to realize that these people also have been lifting weights for years and years so you can't compare yourself to them, you more than likely will never get to that level. Just remember as long as you are eating enough of the right foods and working out three to five times a week, you will begin to bulk up and bulk up to the point of which is good for your own personal body frame and genetics.
Many bodybuilders will proclaim over and over again that if you don't stock up on lots of protein that you simply can't build muscle bulk. Even though protein is one of the main building blocks for muscle, eating tons of protein is going to guarantee that you are going to get more muscle because of it. Your body needs just a certain amount of protein each day and going over that is not going to change things. Since we cannot store excess protein, nor can we get rid of it, the only thing left for the excess protein to do is to turn to fat.
