The nervous system
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring.

Resistance training
Resistance training is any exercise that causes the muscles to contract against an external resistance with the expectation of increases in strength, tone, mass, and/or endurance. Muscular strength and endurance are also important aspects of fitness.Muscular endurance is the ability to lift mild to moderate weight many times. Functionally, it enables an individual to perform a pattern of movement for an extended duration or time. The application of muscular endurance is demonstrated when an individual with a spinal cord injury pushes his or her wheelchair whilst musclar strength is displayed when a wheelchair user gets their chair in or out of a car themselves

Cardiovascular training
There are many benefits of exercising in the Aerobic Zone. This intensity zone is excellent for increasing the number and size of blood vessels in your muscles and improving your lung ventilation. As a result, your body is able to carry more oxygen to your muscles and take away waste products. You also will be burning stored fat for fuel, which is desirable for those who want to reduce body fat and lose weight. This in turn has knock on effects on improving mobility thus helping the individual remain as independent as possible and therefore adds positively to their quality of life.
A regular exercise routine will not only help you feel and look better; it will also produce mental benefits, decrease stress, and increase self-esteem and gives you a more positive attitude in general.
