Mark-Paul Gosselaar is making waves in Malibu! The actor showed off his six-packs and chiseled chest while filming beach scenes for the upcoming third season of TNT's Franklin & Bash on Thursday, Feb. 21.

Sporting a teal swimsuit and wayfarer sunglasses, the 38-year-old actor looked nearly identical to his most famous TV persona, Zack Morris. (Gosselaar played the character on Good Morning, Miss Bliss; Saved by the Bell; and Saved by the Bell: The College Years from 1988 to 1994.)

At the College Television Awards in March 2012, Gosselaar and his Franklin & Bash costar, Breckin Meyer, told Us Weekly how they inspire each other to stay in shape. "He's gotta see me every day, so I want to keep it fresh," Meyer, 38, explained.

"We worked out together the first season," Gosselaar added.

"We did a lot of P90X at one point," Breckin said of the popular home exercise regimen. "It was very exciting. I'm serious!"

The actors try to steer clear of the craft service table on set, but they've been known to treat themselves to Red Vines and apple pie on occasion. "I'll have a drumstick every once in awhile," Gosselaar told Us. "A drumstick is pretty good!"

Gosselaar -- who wed advertising executive Catriona McGinn in July 2012 -- has two children with ex-wife Lisa Ann Russell.
