Greetings and Salutations! (Gee- can't believe Bobby or Kyle missed out on saying this to our new Alien friend!) Welcome Tae-Sung Shin. As to your excercise questions, I've been wondering about this myself lately. I have never heard of weight training for people with cp. In fact several doctors told me any sort of weight or nautilus machines would be counter-productive. They told me NOT to use them when I was thinking about joining a gym. I have no problem with strength. My muscles are like steel! Even when I was a kid, a full-grown man had trouble fighting with my ham-strings and getting them to stretch out. I know weight training is suppose to increase your endurance so your muscles would fatigue less, but what about flexibility? How do weights help? - Denise
