Yoga can be either strenuous or the most low-intensity activity that counts as exercise, depending on how you do it. The low-intensity form is supposed to be warmup or cooldown, or for the elderly and infirm, but mayochuggers do it for half an hour and pretend that it's just as intense as the strenuous kind so they're totally serious athletes you guys. Or they fuck it up entirely and still pretend that they're doing real yoga.
