What harine said. Check out swimming. It's a great source of cardio and isn't quite so intensive on the body as running. On the Wing-Tsun, that's probably a bullet dodged. The legitimacy of it for self-defense or as an applicable to combat martial art's up for debate, and the fact that SWAT was tacked on to the end honestly reeks of "McDojo BS" to me. Granted, certain principles are certainly applicable, especially when applied mixed in with other martial arts, but from what I can tell it suffers from it's own mystique of being "2deadly4u" like a depressingly large amount of traditional martial arts. Aikido's another big one in that regard. Way too few places teach you something that you can apply against a resisting opponent, nor do they train [i]with[/i] any resistance either.
