Wasn't going to say anything, but I am out for now - sidelined at CF. My lower back went down and both hips are #*@%ed. The pain is substantial, can't sleep.
I think that inflexability are a significant part of the problem, as is Arthritis. I have been spending a lot of time in the car traveling and this is not good for the problem.
That article/vid was great. I am off to the "Y" for some easier challenge. My conditioning is fadding fast. Not ready to give up CF yet, but skiing is number one priority.
Appreciate you sharing the knowledge, Lobo.
