Muscles can be found in all of the parts and organs of the human body. Research has shown that males are made up of 42% voluntary muscles while females are made up of 36%. These figures do not include the involuntary muscles such as the heart and stomach.
It is argued that the muscles have the largest capacity for strength evidenced by the nonstop pumping of blood by the heart. Proper conditioning of your body will result in massive muscle gain.
All of us humans are born with the same muscles. They start out small but grow as we go on with our lives. Our different activities contribute to its growth and also explain why we have different sizes at certain points of our lives.
When our daily activities fail to enhance our muscles, we do supplemental activities such as exercise and training in order to build up our muscles. All of the exercises may be done in the gym or at home. The only difference is that we need a little bit of improvisation at home but the effects are the same.Muscle gain can be achieved by following a daily routine of activities as well as eating only prescribed amounts of food during every meal. You may also set a limit to the calorie intake instead of the prescribed foods. Whey protein and other nutrient supplements may also be taken in order to boost the muscle gain of the body.
