What is the best exercise the you learned of in school as part of physical education class?

Jogging because it enhances my libido and makes sex more pleasurable. 

All of them combined prepared me to be stronger and more agile.
 with more stamina. I couldn't choose just one.

square dancing

Self-taught.

Jumping jacks and touching your toes is for rank ametures.

One of my favorite moments was in elementary school, about fifth or sixth grade. The phys ed teacher had a thick rope hanging from the ceiling down to the gym floor. We students were told to, one at a time, climb up about ten to fifteen feet or so and come back down. Most of my classmates seemed to have challenges. All I remember is easily climbing to the very top of the ceiling and back down.
I must have impressed my phys ed teacher because he went and got my classroom teacher and asked me to do it again for her.

My parents remember it, too, because both my classroom teacher and phys ed teacher mentioned it again to my parents during the next parent-teacher conference.

So, yeah, climbing has good meaning for me. :)
