Yeah, more often than not you're not puking because you've reached some "next level physical limit." You've just eaten or drank something that isn't agreeing with strenuous activity. Only times I've thrown up, I've been really far away from my absolute limit and actually felt much better afterward. Guess drinking two glasses of milk before road biking in 105 degree weather wasn't a good idea. Kinda shows just how detached from reality many of these people's grasp of working out is. They've seen too many sports movies where the hard ass but well intentioned coach runs the high school football players until they puke.
