How many out there use push-ups for punishment? Out of the four of us instuctors the school owner is retired military, I was medical discharged after 10 years, another medical discharged after 6 years and the fourth I think also 10. Anyway, the latter 3 of us do not believe in the push-ups for punishment but the school owner does. They are not my troops in the military. I also do not believe in the hands behind the head sit-ups as I have seen too many injuries from pulling on the head and neck region, plus that is one of my spine injuries. What is everyone else's stand?
