I like lifting heavy when I'm a bit buzzed from a glass of wine...I wouldn't venture into highly coordinated movements like Olympic lifting, of course, but suddenly a super-heavy weight on a squat or deadlift doesn't feel as rough. Same with running, I loathe running, but the least arduous mile I've ever run was a "shots mile" (a version of the beer mile but with shots). I don't smoke weed, I only do edibles, and I find those fuck me up too much to work out. I would probably also be unable to control myself laughing at fats at the gym if I went while high, lol.
