Because I look stupid doing them. And I don't see the point, running is far more important than upper body strength, at least for me it is, I mean I'm not running on my hands. And there may have been that one time in gym class where I had to do them but I only managed to do one and then I fell on my face and then the teacher said I had to try again but my nose was bleeding?

[The words just keep coming at this point because really, complaining about gym class memories is so much easier than addressing the actual problem here.]

And everybody was laughing and what's so great about pushing yourself up and down anyway, you look like you can't decide if you want to lie down or not, just make up your mind already?
