How can the nervous system help people get stronger?

The nervous system is an important facet of an exercise plan. In the beginning of an exercise plan, early adaptations and strength gains come from the nervous system. Within two weeks of resistance training, you will become stronger. Each muscle is made up of numerous muscle fibers. Each muscle fiber has nerves attached to it. When we are sedentary, the body will call on as few muscle fibers as necessary to work, leaving other muscle fibers "dormant." When we begin to move more, do resistance training, or participate in challenging physical activity, the muscles are called upon to do more work. When this happens, more nerves are asked to recruit more muscle fibers, which are "awakened" and assist with the activity, thus increasing your strength.
