This isn't much of a testimonial, but that's okay.
I've been doing real CF for about ten weeks now, and I've made lots of performance and overall fitness gains. Though I still have a long
way to go, I'm as happy as can be about the progress that I've made so far in the gym.
For as nice as that is, one of the coolest results came about ten minutes ago, as I was walking down the stairs in my house, grumbling happily about my durned blue jeans and how I have to hold them way up to keep from stepping all over them. Many a year has it been since I've had to deal with that as an issue.
