I used to do Kung Fu for about 2 years, but quit due to the fact that our intructor made us do nothing but push-ups. The previous instructor would give us a warm up, and we would work on exercises that would improve our strength, stamina, flexibility, sparring techniques, everything. The new guy, however, would warm up on his own before class, expect us (even the white sashes) to warm up before class (Shame on you if you were late!), and we would practise every type of push-up and sit-up under the sun for most of the lesson. I was stuck on Orange Sash for just over a year (because they had a timetable which determined which grading work you would work on, and I only needed to finish the Bo form). And all because the head instructor had a push-up fetish. X,(
