Mobility is #1 aging issue
I am attending Mobility Training Sessions.  The ball is great for Arch muscle. Long roller finds hot spots in calves, thighs, hamstrings, groins, etc., and is used to roll out the hot spots, and relax the entire muscle. The back roller can be used on wall, or  even floor.  A large investment in time, but so well worth it.  I have purchased a half dozen of these sets, and given them to session members for their use at home.
