Mark Wahlberg‘s winter bod is putting others’ to shame … the actor continues to flaunt his jacked physique in a pair of shorty shorts while abroad in Barbados.

Check it out … Marky Mark enjoyed some fun in the sun in the Caribbean this week, splashing in the crystal blue water in a pair of itty-bitty patterned swim trunks. The swimsuit’s the same one the action star rocked earlier this vacation, when he showed off his ripped 6-pack and jacked legs for fellow beachgoers.

In fact, even when Mark tried to protect his body from the tropical sun by throwing on a white polo shirt, his protruding pecs were still totally visible.

Between those pictures and these new ones, it’s clear the actor hasn’t missed a day at the gym this holiday season.

This isn’t necessarily surprising, given the fact that Mark has a number of pending projects in the works … including the big-screen adaptation of “The Six Billion Dollar Man” — based on the ’70s TV show “The Six Million Dollar Man,” because hey, inflation.

Despite his busy schedule, Mark is still making time for his family … wife Rhea was spotted taking a dip with A-list hubby earlier in their getaway.

It’s currently unclear if the couple’s 4 kids — Ella, Michael, Brendan, and Grace — joined the pair on their trip to Barbados … but they’re making the most of their time away, nonetheless.
