Forget the gym, it's time to get on that Dancing With the Stars fitness plan!
The former Dawson's Creek alum and most recently DWTS contestant, James Van Der Beek took to Instagram to show off an incredible transformation after dancing his butt for the dance competition.
James posted a side by side shirtless selfie showing off his new physique, writing: "Fight training vs. dancing... I'd been training in Muay 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."
James made it to the DWTS semifinals before being sent home just before this week's season 28 finale—Bachelorette star Hannah Brown took the mirror ball trophy earlier this week.
While James didn't take home the trophy, he still got some abs to show.
In the pictures James shared on Instagram, he looks fit in both if you ask us—but in the second photo on the left, the Dawson's Creek star definitely looked a more defined and toned.
And James hasn't been the only one to show off his major transformation after being on DWTS.
Other stars like Ally Brooke, Lauren Alaina, Sasha Pieterse, Drew Scott, Jennie Garth, Amber Rose, Kelly Osbourne and many others have lost as much as over 40 pounds from being on the show.
