Martial artists are famous for chiseling gorgeous sculptures by striking the stone's pressure points, composing symphonies from the screams and moans of defeated enemies, and destroying opponents with Mortal Kalligraphy. Get inspired by a different kind of martial art with today's deal: for $30, you get one month of multiple classes at Dynamic Martial Arts of Sioux Falls, located at Sioux Empire Fitness on South Tennis Lane. The dojo's class schedule offers weekend and evening classes so that you don't have to skip work to learn how to defend your village from bandits. Call ahead to reserve your spot.

Dynamic Martial Arts specializes in jujitsu, a Japanese martial art grounded in Samurai tradition. Since it doesn't do much good to hit an armored opponent and takes all night to seduce them out of their armor, schools of jujitsu place the most emphasis on throwing, joint manipulation, ground locks, and using an opponent's energy against them. DMA will tutor you in all these aspects. And since jujitsu involves getting thrown as much as it does getting to throw others, DMA's senseis also teach you the vital art of falling down without hurting yourself. In addition to unarmed fighting, DMA offers a traditional Japanese weapons class twice weekly, which is under the strict safety supervision of DMA's highly trained instructors rather than some guy in a trench coat clutching a toy lightsaber.

Because taking up a new martial art can be as intimidating as performing stand-up at the Outdoor Heckling and Tomato Chucking Festival, the calm, no-nonsense atmosphere of the DMA school offers an approachable sanctuary where you can start down the black-belt road—a road paved with discipline, focus, physical fitness, and mooks who politely attack one at a time. The website offers advice to ease first-day jitters, numerous inspirational photos, and one sick display of bare-handed fruit-fu, the likes of which has not been seen since sensei Gallagher was killed in combat by a vengeful watermelon. Every great journey begins with a single step, so get in shape, blow off stress, and learn to defend yourself against the neighborhood's samurai bully with today's Groupon to Dynamic Martial Arts of Sioux Falls.
