<passage>:
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. Kung Fu Reputation: 1960s martial arts movies Bruce Lee. Intimidation Factor: 4 In the all-levels group I observed at Seven Star Women's Kung Fu, there were a dozen or so women dressed completely in black. (Most classes I took were co-ed.) The school wouldn't let me take the class--I could only watch--but that was better than Temple Kung Fu, which made me sit for an interview before they'd even reveal any information on their classes. There seemed to be an active screening process to keep out those with only a casual interest. Strength Workout: 3 and the lower body, from the kicking. It was not extreme, and nobody seemed exhausted. Aerobic Workout: 2 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. 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 lots of kicking the martial art of the 1990s. Intimidation Factor: 1 I was instantly welcomed into the beginners class at Lee's Martial Arts. People called each other by their first name there was laughing, joking, and none of the aloofness or self-importance of the kung fu class. Strength Workout: 3 This rating is a little misleading. The lower-body strength workout was fantastic--my legs and hips were sore for days--but there was almost no strength training for the upper body. We used our arms only for balance and blocking kicks. Aerobic Workout: 5 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. 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 We started with sit-ups and push-ups, which were the most demanding parts of the class. The kicking and punching made for decent exercise, but I wasn't aching the next day. The drills (lots of punches, blocking, and kicking) provided some aerobic workout, but were not particularly intense. Coordination and Balance: 4 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. 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. 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. 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. Strength Workout: 2 Aerobic Workout: 0 Tai chi involves moving your body slowly in circular patterns, shifting weight from foot to foot, and lifting your arms in rounded gestures, all at a pace slower than you ever thought possible. The motions had names like "parting the wild horse's mane" and "repulsing the monkey." I did not break a sweat, but I was bored to tears. Coordination and Balance: 4 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. Intimidation Factor: 5 Although the listing in the phone book advertised the "Brazilian Jiu Jitsu Academy," the sign on the door said "Northwest Fight Club." Inside the club, huge holes had been punched in the walls--some back-size, some fist-size. Huge letters painted on the wall said "TRAIN &amp FIGHT HARD." The instructor, a handsome young Brazilian man, had a long scar curling out from the left side of his mouth and a fresh-looking purple one by his left eye. When I asked to try the class, he shrugged and lent me a gi (the white outfit most martial artists wear), on the back of which was a drawing of massive snarling pit bull and the slogan "PIT PULLING PURE POWER." I wondered if I was going to need an ambulance to take me home. Strength Workout: 5 The next day every inch of my body was sore--my stomach, arms, legs, feet, and neck. For Olympians only. Aerobic Workout: 5 This ranks as one of the hardest and most complete workouts I've ever had. After some stretching, we launched directly into hundreds of lightning-fast sit-ups, crunches, push-ups, leg lifts, and scissor kicks. I was quickly panting and my face turned a deep fuchsia. We did forward and backward rolls, learned to escape from various holds, and executed the sort of belly-crawl that marines always seem to be doing in movies about basic training. After an hour and a half I felt close to death, but there was still another hour to go. Coordination and Balance: 2 Coordination is important, but since you're tussling on a mat most of the time, balance isn't. 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.
