How We Move: The Gross Anatomy of Motion | Wondrium
I have been watching this and would probably get too fixated on figuring out which muscles were working and their names if viewing naked pickle ball players.
Years ago I used to walk around Doggie Doo Run Run's back field with a pickleball teacher who taught here in the Villages. She had fun teaching the Villagers pickleball.
I do not think she took into account a lot of things flopping around that should not be doing that if these pickleball players became naked.
