Mark Wahlberg's swole body should be motivation to hit the gym -- at least until you quit your New Year's resolution in 3 weeks -- but his diving form might need some work.
Mark's been vacationing in Barbados with his wife and 4 kids and having a blast ... as you can see in these pics of the action star attempting a dive off a doc into the Caribbean.
Take off was strong, but midway Mark looks like he's heading for an awesomely painful belly flop.
Check out the gallery to see if he pulled it off in the end.
