You should seriously think about starting to go to gym so sports like: running and swimming. This two are the best. A lot of people ask me about proteins. After doing some research on my own (even on my own body) I can tell you that in general proteins are a good thing in the life of an athlete. People that don't know too much about them just presume that they are something bad and confuse them with steroids and other bad things. This is simply not true. If you are serious about building your muscles taking proteins is a must.

   They are the building blocks of the muscles and they should be taken in them morning and before work outs. There are a lot of proteins but the whey protein is the most used one because the effects are a lot faster. You normal meals are not enough to provide you with the necessary vitamins and proteins your body asks for. By not taking them and by doing a lot of effort you risk to damage your body instead of taking care of it.
