Um… clearly Dancing with the Stars has done wonders for James Van Der Beek’s physique.

The actor recently posted a shirtless selfie after competing on season 28 of DWTS — and we’re aghast!

“Fight training vs. dancing,” he captioned a photo. “I’d been training in Muy Thai three days a week for about six months (for the next project I’m writing) when I hit pause to dance six hours a day. Now I can rhumba.”

You can rhumba all day, James!
