A question about "Becoming a Supple Leopard." How does it stack up against Feldenkrais? Or Adrian Crook's Inflex, if you've run across it. I'm a former Tai Kwon Do practitioner who has become very inflexible, and I'm hitting the gym to reverse the effects of personal sloth. Any tips on flexibility regimens is appreciated. 2 knees and 2 hips substituted with titanium, so no running or skiing, which sucks.
