So I started out flexibly-challenged and after biking for 10 years it's even worse. I finally started stretching about 3 years ago when I realized I was turning into the human equivalent of a clenched fist. I've taken up T'ai Chi and do hamstring stretches each time I come back from a ride but I'm never going to be Gumbie-woman. What does everyone else do to keep from seizing up entirely?
