Here is a clothed version of Totally Nude Aerobics for contrast. The same exercises and music are used in both. I believe the ladies were told to mouth-breathe because it looks more hot. You might enjoy this video along with some Wayne King. Link in comments.
Another project after THUNDERBIRDS ARE GO from Gene Anderson. It was meant to titillate Dad and steer Junior towards heterosexuality - that's my theory anyway. Supermarionation is melded, invisibly, with live-action. The DVD set has gone out-of-print and so this show is ours to enjoy.
