I have never experienced it. Even when I was very physically fit (I was a martial arts instructor in college), I never got any pleasurable sort of feeling from working out. I enjoyed the activity itself, but the end result was always exhaustion and a vaguely nauseous feeling.<p>Considering other things that are supposed to make you feel &quot;high, aka good&quot; (like the Vicodin I had been prescribed when I got my wisdom teeth forcibly removed from my skull) also only seem to make me feel generally nauseous, I&#x27;m guessing this is just me in general.
