Being able to do a push-up eventually would be cool. I never really managed any, not even as kid in school. Now having read more about various exercises and about variants and such, it's another thing that is making me even more disgruntled with my PE teachers in retrospect, because back then I just failed at doing push-ups, but none of the teachers offered systematic alternatives, and I just tended to sit out the stuff I couldn't manage. And none of the condition or strength building stuff was done systematically or with decent explanations anyway. It was all just done in a quick prelude to other sports stuff, like various team sports or track and field.

Looking back I realize more and more that there were actually necessary physical education things they should have taught us in that class that would have been relevant for me, about how our bodies work and about maintaining health and mobility with the actual body you have to work with for your everyday life. But their completely idiotic emphasis on complicated team sports and athletic disciplines turned out to be way worse than with other skills taught in schools.
