Bodybuilding involves more than just lifting weights. It pays to have an understanding of human kinetics. How do muscles work?
For the full science of muscles, check this out.
Muscles develop by making them work. Muscles can only work when the body is in motion. They work extra when we are in full motion. Thus, to develop the muscles to the maximum, we must make them work to the best of our abilities. Hence, the bodybuilding principle of “No Pain, No Gain.”
You can’t grow your muscles by doing anything. You have to move around a lot. The only thing that will grow in points of inertia, if you remain stationary, is your weight.
If you want muscle growth and power, you must work your body methodically. Muscle training is called a workout. Muscles can be toned (or conditioned) by regular activities like brisk walking, jogging, and doing other slightly heavy work. But toning muscles will not grow them in size and beauty. You have to do more —lots more — to have stunning muscles.
You have to work out. By the very term “workout,” you can have a good idea of what it takes to grow muscles. Bodybuilding procedures using weights and other heavy-duty activities are the best-known muscle growers so far. You have to devote your life to this if you want extra visible muscles on you.
You also have to do away with vices like smoking, drinking liquor, eating junk foods, etc (at least most of the time).
Muscles grow in size only when they are moving. Try to be still in front of a mirror and you’d see no sign of any bulking muscle taking shape. Now, clench your fist hard, and muscle evidence will show at least on your forearm. This simple principle illustrates the potential of muscles being developed through repeated and graduated motions.
As muscles are subjected to repeated exertions that gradually increase the intensity, they grow and toughen. The more intense the muscle activity, the better and faster the muscle is developed. Hence, a systematic muscle development program incorporating increased muscle stimulation builds more muscles effectively.
If your exercise features no such system of increasing efforts and challenges to your muscle strength, your muscles can only grow so much. Some exercises do form muscles, but only to a certain extent. The muscles built only become regulating muscles that enable you to perform normal tasks effectively.
But they cannot exceed performing beyond such tasks. On the contrary, a fully developed muscle does not only allow you to do normal tasks; it is calibrated to reach its full potential — far beyond what regulating muscles can do. Bodybuilding helps you develop your muscles to the extreme.
