"I have my own workouts, but for these particular weights...lemme see..."
I know Tony's here, and Baird, and I think there's another inventor too...
"Bingo!"
With a triumphant grin, he twists a plate off the end of one of the free-weights, revealing a simple set of dials and buttons.
"The Xavier Institute's a school for mutants...that's Midgardians born with special powers that set them apart from baseline humanity. I figured with all the ones with super-strength that come through here, Professor Xavier would have some special exercise equipment, like my friend Tony Stark does in Avengers Tower."
He points out the controls.
"Yeah...see these? Looks like you can set these as heavy or as light as you want them to be, to give yourself an actual workout rather than just moving your arm up and down."
So where was this ingenuity when they were hanging punching bags? he thinks with a wry smirk.
"So you can get a workout if you like. Of course, I'd love to join you for breakfast, if you are done."
