“Muscles”, there are three types of them Cardiac, smooth and skeletal muscles. Building muscles usually refered to building skeletal muscles
While you use your muscle to lift something, your muscle experience some tiny tears in the muscle fibers. This is the first step of muscle growth. So, tiny tearing of muscle fibers is good in this context. When muscle breaks, something called cytokins are released. These repair the muscle, that’s the time when the muscle grows.
But the correct amount of tension is required for a muscle to undergo tiny tears, which with the help of protein leads to muscle growth. That’s the reason why body building experts suggest to increase tension in the muscle gradually. In other words, gradually increase the weights you lift.
On the other hand, people who do calisthenics or body weight workouts, must know how to increase tension by incorporating compound movements where ever possible. Calisthenic exercises mostly have compound movements, which is good and absolutely helps build muscle. Personally I feel body weight workouts are the best. Because there is a lesser scope of getting injured, it has compound movements and the “burn” we feel after an intense body weight session is amazing.
The “burn” you feel after an intense workout is simply an infusion of lactic acid in the muscle, which is produced as a muscle burns its energy stores. The pump you feel when training is a result of blood being “trapped” in the muscles.
If a workout causes too many micro-tears, then the body will fail to fully repair the muscles, and muscle growth will be stunted. If a workout causes optimal micro-tearing but the body isn’t supplied with sufficient nutrition or rest, no appreciable amount of muscle growth will occur.
Building is all about exercising with correct tension, sufficient amount of rest and good food! And to take every nutrient correctly, for proteins sources, read more about the protein sources here Top 5 vegetarian protein sources.
