People usually do not really know what makes their muscles grow bigger as they lift weighs at gyms. They see their muscles getting bigger without understanding the logic behind. Here is a very easily explanation. There are three types of fibers in the muscles. Slow twitch fibers, Fast twitch fibers-A and fast twitch fibers-B

The survival capacity of slow twitch fibers is high. They are therefore used when a person is running to cover a long distance. Such fibers don’t produce lots of forces but they do help the body continue doing the activities as they don’t get tired easily.

Low weight repetitive trainings even can excite theses muscles. However you cannot expect these fibers to help in increasing the mass of the muscles. A long distance runner’s body is always smart as these fibers remain active all the time.

Fast twitch fibers are however strong and create lots of force. But they also get tired easily. The fast twitch fibers B are however more powerful than A and also get tired a lot faster than A.

These fibers utilization is in such activities as weight lifting and running. If you get heavy weight lifting training, these fibers in your muscles will get stimulated and developed. This will lead to massive muscle gain. Bodybuilders and football players have these fibers developed in their body so their body is heavy and giant

The composition of muscle fibers is not in the same proportion in all people. Some people have large number of fast twitch fibers in their muscles and others have large number of slow twitch muscles. This is why the skinner people do not put lots of weight on them even when they try it.

The decision of which exercise you should choose depends on what sort of gain you want for your body. If it is fast muscle gain, go for exercise that trigger the fast twitch fibers and help your muscles grow.

On the other hand if you want your body’s endurance to increase, focus the slow twitch muscles stimulation and growth.
