Self defense only?

Martial arts is not only for self-defense  it changes you. Among  the early changes seen when individuals engage in a  Martial arts training program is mood elevation, heightened energy levels, enhanced self- confidence and self-esteem, lower anxiety levels, resistance to depression and improved coping ability. Changes translate into better functioning of the body and brain, and overall risk reduction for such diseases as hypertension, type 2 diabetes, coronary heart disease, chronic respiratory disease, osteoporosis, obesity, anxiety states, mild to moderate mental depression, and chronic fatigue. Martial-arts-style maneuvers are much more than self-defense they're proven calorie killers that burn an average of 500 of those suckers an hour.
