Michael Myers Gets In Gym Workout For Halloween Prank

Michael Myers was killin' it at the gym this week.

Sorry, had to.

Former pro pitcher Logan Chitwood gave meatheads a scare at the gym this week -- by dressing up as the "Halloween" villain and getting in a workout!!

The hilarious prank was caught on video ... showing the YouTube star working on his biceps and triceps while decked out in the slasher's navy jumpsuit, mask, wig, and boots.

Chitwood stayed in character the whole time -- you can even see him holding a fake knife while pullin' this off ... but he did struggle a bit when he tried to do a one-armed pull-up.

The prank got a mixed reaction from the folks at the gym ... with some laughing and recording while the serious gym rats stayed focused.

You know who thought it was hilarious, though?!? LeBron James ... saying on his IG, "That some 💩 I would do!! 🤣🤣🤣🤣"

In fact, the NBA superstar -- who seems to be a huge Michael Myers fan -- has a fake replica of the slasher at his mansion for Halloween decor and recently watched the new "Halloween Ends" movie.

"Halloween Ends was so GOOD!!!!" the 37-year-old said on Twitter, "@jamieleecurtis you're such a LEGEND & BADASS #MichaelMyers"
