OK guys... CFSF hopes that you all had a WONDERFUL Thanksgiving. Thankfully, IT'S OVER! We are back on schedule right up until Christmas. Did you check out the mobility blog over the break? Get any for yourself ?  Hope so. This video is a great little demo of the hollow rock. If your lower abs are weak, you will CLUNK, not rock. This will be part of Monday's warm-up. See you then.
