My recent reentry into the martial arts world agrees with Jeff's assessment. I've just started playing around with Krav Maga. Ask me to throw a jab, cross? - no problem; shin kick to the side of the leg? - feels like I'm getting back on a bike; ask me to efficiently pluck an attacker's hand from my throat or punch while NOT retracting the opposing hand (you know, the one that's holding the barrel of a gun AWAY from your body) - I feel COMPLETELY retarded.
