Tom Holland, 24, has been working on his fitness in quarantine! The British actor was in the best shape ever as he showed off his toned abs and buffed up torso in a shirtless pic posted to his Instagram account on Sunday, July 11. “When working with @markwahlberg you gotta get after it,” he wrote over the photo, shouting out his ripped co-star Mark Wahlberg, 49. Tom’s arms were also looking so defined in the pic as he opted to go clean-shaven.
