James Van Der Beek took to Instagram on Wednesday to share two shirtless selfies -- one taken before he joined Dancing With the Stars and other taken after he left the show last week. 

While the 42-year-old actor looks ripped in both pics, his muscles are much more defined in the second image. "Fight training vs. dancing..." Van Der Beek captioned the post. "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 ??."

The Dawson's Creek star made it to the semifinals of DWTS and ahead of Hannah Brown ultimately taking home the mirrorball trophy, Van Der Beek posted about his time on the ABC show along with a video of his and partner Emma Slater's samba. 

"Yet another life lesson reinforced for me at 42 on this crazy reality show dance competition ?." he wrote in part. "If you’re feeling too old to pick up a new skill you always wished you had... f**king go for it. #LightItUp"

ET was with Van Der Beek and Slater at their rehearsal ahead of his final night on DWTS. Here's a glimpse of how he managed to get those washboard abs:
