Increasing your flexibility can increase your performance in physical activities which will only lead you to having more energy, more reps, and last longer in the gym than without stretching. 

Stretching will certainly decrease your chances of injury by helping your muscles and joints move fluidly through their full range of motion. Avoiding injury is extremely important so that you

do not damage your muscles or ligaments for good or at least set you back a few weeks while you go through recovery.

Stretching your connective tissues that surround the muscles will expand the fascia and enable the muscles to grow bigger and stronger.

Do you ever see those extremely large muscle men with a big hunch when they walk? Chances are they don't stretch! When you don't stretch your muscles after workouts—especially after

heavy weight lifting—you are training your muscles to be compact. You want your muscles to be long and lean to support your back and give you a great posture. A

good posture is better for your health and will have you looking more confident.

After you release your stretch, your blood flow exerts nutrients into your muscles. This release of nutrients transports protein that will lead to muscle growth.
