There are many particular areas of health that men are interested in, but one that appears to hold the interest of most men that are interested in doing something about their personal fitness is muscle mass.
Muscle mass is, of course, a big part of personal fitness and of course, a person that has a larger and leaner muscle mass will be able to do a number of heavy lifting and endurance tasks that other people will not be able to do.
This is why athletes work on lean muscle building on a regular basis; in order to allow themselves to work on even harder personal fitness exercises that require a larger and leaner muscle mass.
One of the ways in which you can create this lean muscle mass all over your body is to increase the amount of smart protein that you take in. If you exercise through cardiovascular work on a regular basis then you already know that the more you exercise the more you can take into your body in terms of food and sustenance.
However, there are still certain foods such as fried and battered foods that tend to pump a lot of unnecessary fat and cholesterol into your body that you simply will not have enough time to get rid of even if you exercise a great deal.
Consuming protein on a regular basis however through the ingestion of lean meat and meat substitutes will allow your body to have the nutrients it needs to build up a very impressive and very lean muscle mass through the exercises you perform.
