5 BEST MUSCLE BUILDING EXERCISES!

 When it comes to muscle building, it both depends on the type of exercises that you do and also on the lifestyle that you follow. Inside the lifestyle, the number of extra activities, the amount of rest, and most importantly the food that you consume, everything counts if you have a muscle-building oriented target. This blog is all about those main exercises which one must do or perform to develop muscles but before that one must know the science of how a muscle grows because of these exercises. The reason behind this is, if you do not have an idea about the mechanism of growth of a muscle, then all the efforts might go into vain. The following points will clear all your doubts.

HOW DOES A MUSCLE GROW? First of all, we must all know that during exercise or maybe during any normal activity, there is the lengthening of the muscle as well as the shortening of the muscles. The shortening of the muscles is called the contraction and the lengthening is called the eccentric part of the motion. Now, we should know that the skeletal muscle is made up of muscle fiber bundles and these have long cylindrical cells that can contract or relax as soon as it gets signals from the nervous system through the neurons to the neuromuscular junction. Each of these fibers is constituted of sub fibers called myofibril. These individual constituents consist of a thick and thin filament that can move backward and forward if any kind of contraction is done on the muscle. During this entire process of contraction, ATP ( Adenosine triphosphate) is needed, which is the main source of energy and that we get from the food we consume. After the contraction is complete and we reach the fatigue point, the muscle fiber increases by then because of the accumulation of the thick and the thin filament in the muscle fiber. Hence we can say that muscles grow because of some heavy stress. For example, when someone is trying to lift heavy, the muscle undergoes tremendous stress and as a result, the size of the muscle grows. If we see at a molecular level, there are many micro-tears of those fibers and as we lift the weight, we get lots and lots of little tears just like a dough when we stretch it. Now when we give our body proper rest and food, all the repairs are done as the reattaching of the muscle fibers is done along with the attachment of few extra muscle fibers and this, as a result, will make the muscle grow.
