One day, a budist discobered that activity was good for him and the other budists monks. So they started doing exercise. After years, that exercise they were doing, became a fight style: kung-fu
If you dont move, meditation will be very hard. So start doing some sport before meditation. You also can try a martial art class which have meditation. Tai-chi, Kung-fu, Aikido, Chi-kung, Karate.
