Here's some I like for work outs (politics of the performers not considered).
Grace Potter and the Neanderthals “Paris”
Tom Petty “Runnin down a dream" and “You wreck me”.
Pearl Jam “I am mine”.
The Beatles “Get back”
If I was picking some Yes for a workout I might go with something off of Relayer, or maybe South Side of the Sky.
Best Yes Song would be “Tempus Fugit”.
My Yes song is “Leave it.”
“Red” by King Crimson
I dunno about that; Gates of Delirium comes to mind....
