Falling asleep during yoga (or on a weight bench, etc.)
There was a man in my yoga class who would invariably fall asleep during the corpse pose. Not only fall asleep, but snore. LOUDLY. I was always happy for his relaxation (because, by that point, I was totally zen), but it really kept me from reaching the state of relaxation I desired. And, if you're so tired that you're falling asleep on the weight bench? Go to bed earlier! Skip the gym one day and get some sleep. It's good for you!
