James Van Der Beek's before-and-after "Dancing With the Stars" photos will have America doing the rumba to trim down after Thanksgiving stuffing.

The "Dawson's Creek" star, 42, showed off the shirtless display on Instagram Tuesday, highlighting the impressive results from his hard work on the reality dance competition, which ended Monday.

The first photo showed Van Der Beek looking buff before the show started. After all, he's James Van Der Beek. And, as he said in the caption, he'd "been training in Muay Thai three days a week for about six months" for the next project he's working on and writing.

Then he hit "pause to dance six hours a day" on "DWTS."

"Now I can rhumba,"  Van Der Beek wrote in the caption of the shirtless photo showing him even more ripped after the dance competition. The gold chain on his neck in both photos is there for scale on his ripped-ness.

Van Der Beek had been one of the best dancers on "DWTS" before he was eliminated in the semi-finals, on the same night he released the news that his pregnant wife Kimberly had miscarried. It was controversial and heartbreaking.

The actor and his wife showed up on the finals on Monday and were the essence of class in the face of his booting from the show. Van Der Beek simply wished top Hannah Brown all the best in her Mirror Ball Trophy win.
