Martial Arts are good and help out physically. But internal martial arts(chi gong, tai chi, falun gong...etc.) are where you can really gain a lot of spiritual power. The foundation of Satanism being meditation and spiritual elevation, your aura needs to be strong in order for you to work magic and advance to higher levels. This can be achieved through yoga and mantra work and other ways such as internal martial arts. Internal Martial Arts work to strengthen the aura in a different way yoga does. Yoga is more powerful however.
