Micro tears are rips in the muscles that are filled with fibers making the muscles grow bigger and bigger as the time elapses with daily training, The fuse of fibers form new muscle protein strands or fibrils. Microfibers are created when the production is bigger than the break down of the of the fibers. When resting these fibrils start to collect inside the micro tears making the muscle bigger.
in order to grow muscles make more muscle tension than the one that the body already supports, by lifting heavier weight than the actual body weight will create tension in the muscles. After working out there is something called satellite cells which jump in while the muscles are damaged. There is metabolic stress which causes the cell to swell making the muscles larger. After the work out resting is the most important part so muscles can grow.
