United States Martial Arts Systems on La Mesa Boulevard in La Mesa Village teaches six disciplines — Taekwondo, Hapkido, Judo, Jiu Jitsu, Kendo, and Iaido — under the World Martial Arts Tang Soo Do Federation banner. The multi-art curriculum builds rotational striking and board-break power through Taekwondo forms while layering Hapkido joint locks and Judo throws for close-range grappling, a stand-up-to-ground progression that complements the flexibility conditioning available at CorePower Yoga - La Mesa. Every class is supervised by an instructor holding at least a 2nd Degree Black Belt, with a Master Instructor present at every session. The school has trained students continuously since 1994, advancing ranks from white belt through advanced black belt levels for ages five through seniors. Spinal alignment and joint health are critical for high-kick practitioners, making routine care at La Mesa Spine Center a natural complement to the rotational demands of Tang Soo Do training. Advanced students train traditional Japanese sword arts — Kendo with bamboo shinai sparring and Iaido with live-blade drawing kata — adding weapons-based precision to the empty-hand core.
