Mark-Paul Gosselaar is in very good shape these days, continuing his heartthrob status from the Saved By The Bell Days, only now instead of gracing the pages of Tiger Beat, he’s sharing nude pics of himself at the gym.

The 41-year old actor announced recently that he and friend Ben Ceccarelli are partnering up for CrossFit’s Powerpair Competition and shared a photo of the two of them doing handstands completely nude, cheekily calling themselves “Team Cocky”. This week, he’s hitting the gym again and can be seen on Instagram a bit more covered but still shirtless, hanging from a bar as he photobombs some other gym goers.

Gosselaar, who recently reunited with his Saved By The Bell costars for Jimmy Fallon on the Tonight Show, isn’t afraid to show off his assets; he’s bared his behind on Franklin & Bash and Weeds in the past and didn’t think twice about it.

Gosselaar announced last month that he was a new dad again after his wife, Catriona, gave birth to their daughter. It’s the fourth child for the actor as he has two children from a previous marriage, but he said he and his family were so excited to expand.

“It’s something we’re really excited about and we’ve been planning for awhile. We’re doing some tweaks to the house and some things to prepare for the room. But we’re old pros at this now. How do you prepare other than get as much sleep as you can?” he said.
