Krav Maga, hmmm, pretty... trendy. Get on it!

Is it? I had no idea, been thinking about it for years.

"Karate? Karate is like the Dane Cook of martial arts. We do Krav Maga."

sounds good man, let us know how it goes!

I've started taking Tai Chi (as the martial art, not some other focus) as of the end of April myself.

For me, I like Tai Chi's more defensive style, it's easy application for improving general health, and its relevant philosophies.

The philosophy of T'ai Chi Ch'uan is that, if one uses hardness to resist violent force, then both sides are certain to be injured at least to some degree. Such injury, according to t'ai chi theory, is a natural consequence of meeting brute force with brute force. Instead, students are taught not to directly fight or resist an incoming force, but to meet it in softness and follow its motion while remaining in physical contact until the incoming force of attack exhausts itself or can be safely redirected, meeting yang with yin. Done correctly, this yin/yang or yang/yin balance in combat, or in a broader philosophical sense, is a primary goal of t'ai chi ch'uan training. Lao Tzu provided the archetype for this in the Tao Te Ching when he wrote, "The soft and the pliable will defeat the hard and strong."
