<passage>:
Kick Me To find out, I tried a handful of karate, tae kwon do, aikido, jujitsu, and kung fu classes in the Seattle area. I scored each one in several areas: how intimidating the class would be to a novice how much the exercises worked my muscles how much of an I got whether it would develop coordination and balance how much physical contact with other people was involved and, of course, its value in self-defense. All ratings are on a scale of one to five, with five being the hardest, most intimidating, or most valuable. To experts, this will look like a hopelessly biased and superficial inquiry. It is. But to beginners, it is one step toward figuring out which martial art might be right for you. Do you want a chance to kick the stuffing out of someone? Take tae kwon do. Do you want to improve your sense of balance? Take karate. Do you want to know what to do if someone tries to choke you? Take jujitsu. Just remember that if you're jumped by a mugger, the only thing Tae-Bo will be good for is making your attacker collapse into uncontrollable fits of laughter. Kung Fu Reputation: 1960s martial arts movies Strength Workout: 3 After meditating for a few minutes, students launched into traditional strengthening exercises (push-ups and sit-ups) and then broke into pairs, with one person kicking pads held by the other. It looked to be decent strength training. Their arms got a good workout from the push-ups and punching abs, from the sit-ups and the lower body, from the kicking. It was not extreme, and nobody seemed exhausted. After the strength work and partner work, the class broke into a few groups (according to skill level) and repeated choreographed routines called "kata ," which involve a series of punches, kicks, and blocks with an imaginary foe. The class had broken into a light sweat, but was not gasping for air. Coordination and Balance:                 4 The rounded slinky movements of the dancelike kata looked specifically designed to develop grace, coordination, and balance. Degree of Contact: 1 Almost none. No direct body-to-body contact, but plenty of punching and kicking with pads. Self-Defense Value: 2 The moves were neat to look at, but they did not seem practical. And without sparring practice, it would be difficult to apply the drills in real life. Overall: Kicking, punching, and an aura of mystery. Tae Kwon Do Reputation: World's most popular martial art, new Olympic sport lots of kicking the martial art of the 1990s. Intimidation Factor: 1 there was laughing, joking, and none of the aloofness or self-importance of the kung fu class. Strength Workout: 3 We began with everyone standing in lines and kicking into the air. Then we did a long series of running drills up and down the mats. Then there was more kicking: Turning kicks, straight kicks, low kicks, kicks with punching bags, kicks with partners â€¦ the list goes on. It was an excellent workout. Coordination and Balance: 4 Learning how to make contact with the pad (and not, say, the face of the person holding it) was important. Balance was crucial in the sparring. Degree of Contact: 4 At the end of class came a session of sparring (which I, alas, was not allowed to participate in). The students strapped on protective chest pads and helmets and began kicking the stuffing out of each other. Self-Defense Value: 4 Tae kwon do emphasizes sparring and gets students accustomed to dealing with an assault. Overall: More a sport than an art will make short work of flabby legs. Karate the martial art of the 1980s. Intimidation Factor: 1 When I watched a class at the Feminist Karate Union, I asked some of the students how their class was different from the Seven Star Women's Kung Fu class, which is held in the same building. One woman immediately said, "Oh, kung fu? That's what the mean people downstairs do." This class was approachable and open. And karate's so familiar that you feel like you already know how to do it. Strength Workout: 2 The drills (lots of punches, blocking, and kicking) provided some aerobic workout, but were not particularly intense. Coordination and Balance: 4 Keeping yourself centered while kicking and punching develops your balance. Degree of Contact: 2 There was some contact in the paired kicking drills with a partner and pads, but most of the physical contact came during the sparring. Yet this was nothing like the tae kwon do sparring: They weren't clocking each other, just repeating the motions of punching and blocking over and over again. Self-Defense Value: 2 This was entirely focused on form no full-force contact between students. Overall: Kicks and punches galore, with a dash of moral and spiritual teaching about self-discipline and obedience. Aikido Intimidation Factor: 1 Despite its reputation, aikido is decidedly nonaggressive--it's about deflecting punches and immobilizing your attacker--and there was a mellow, pleasantly upbeat atmosphere to the class. Strength Workout: 3 No sit-ups or push-ups, but pulling and yanking on other people looked like it would build muscle, and the rolls worked on your abs. Coordination and Balance: 5 The goal is to destabilize and control the other guy, so maintaining your balance--and learning to topple your opponent--is crucial. Degree of Contact: 4 To complete the partner exercises, you had to grab your partner, spin him this way and that, and generally come in very close contact. Self-Defense Value: 5 Learning how to neutralize a threat was the main goal of the class. Overall: You don't get to land any punches and it's noncompetitive, but you'll learn how to knock people over. Tai Chi martial arts for seniors. Intimidation Factor: 1 I found its New Age connections slightly off-putting, but it looks so easy to do that it wasn't daunting. Coordination and Balance: 4 Balance and control of your body position are the heart of this art. Degree of Contact: 0 Self-Defense Value: 0 I learned how to repulse a monkey, not a person. Overall: A yawner, slightly embarrassing to perform, but I'm sure if done correctly it brings high-quality inner peace. Coordination and Balance: 2 Coordination is important, but since you're tussling on a mat most of the time, balance isn't. Degree of Contact: 5 Self-Defense Value: 5 Jujitsu's few-holds-barred grappling is far more effective when push comes to shove (and worse) than standing arts such as karate. Overall: Lots of grappling, throwing, and choking. Pragmatic, not pretty. High badass quotient.
