Why muscle supplements? Why do you need to pay attention to supplements when you can just exercise, right? Although it is true that exercise plays a very large role in building muscles, it simply is not enough to get those muscles growing. If you want to gain muscle mass and get ripped you have to get eating down to a science. Simply put, you can't build anything that isn't there, so to be able to bulk up you have to learn what raw materials your body needs to start building muscle mass first before doing the exercises to shape up.
Why are muscle supplements important? Because they're full of something muscles need, protein. Protein is a food source that your body can most easily convert to muscle when it's digested. All foods you eat have energy units called "calories," which you need to keep your body running right. You get your calories from carbohydrates, fats and proteins. Protein calories most easily convert to muscle mass. You can get a lot of protein if you consume protein rich foods like meat or eggs.
Why do you need additional muscle supplementation, then, instead of simply eating more protein rich foods like meat and eggs? Because protein isn't all you get when you eat meat. You are also going to be eating fat. You only need a small amount of fat to be healthy, and the extra fat that comes in these types of foods is very easily stored. This can make you gain more fat instead of muscle. Proteins are broken down when they're cooked. And it's not a good idea to eat raw egg whites, either. Although you might think this is a good idea, you can get salmonella poisoning from doing so. In addition, eating the whites but discarding the yolk is a big waste of food.
Muscle supplements can give you a safe, high dose of protein that's easy to take. Once you have enough protein in your diet, the next thing you need to do is to concentrate on bulking up the part of your body want to be the most muscular. That is, you "strain" the muscles you want to build up. When you strain these muscles, you break them down. They build back up using the protein you fed your system, and they come back bigger and stronger. This is so that they can handle the added strain you're giving them. But of course, a good side effect of this is that you get bigger, leaner muscles.
Once you get the protein in your system it would only be a matter of concentrating activity. As most trainers would suggest, work your muscle groups to failure. In other words, concentrate activity on a muscle until it cant take it any more. For example, if you would like to make your biceps bigger then keep doing bicep curls until you cant lift your weights any more. This tells your body to compensate for the strain by adding more protein for muscle mass, making the bicep grow bigger and stronger.
So as you can see, muscle supplements are ideal for muscle building. And better yet, these supplements come in many different forms that are convenient to take, like pills or drinks.
