Dwayne Johnson is now 45-years-old, but he's far too busy to think about having a mid-life crisis. Somehow, in between shooting and producing blockbusters, meeting fans, making media appearances and paying a visit to his old WWE stomping grounds, he's found time to get in the weight room and lift some 175 lb. dumbbells (or as he calls them, "Kevin Harts.") Here are some of the best photos of those workouts that he's put on Instagram. You're welcome.
