The very best program for those of us that cannot get down on the floor, those of us that do not want to go to a gym, etc..Really this is the greatest program around for those over a "certain age" Seriously. I retired and became a couch potato, and could feel myself declining physically..Started GYF and was not consistent for quite a while..About 6 months ago I started taking it seriously and now, I am within a few pounds of goal, able to walk better, overall feeling so much better..Keep It Moving'.You will not regret it..Best gift you can give yourself.
