What an idiot. As if you tell people to try than on concrete steps with people walking past. If you want to learn how to do that (it's relatively easy if you have good core strength) do in on the mats at the gym with an instructor supporting your back and if you need it giving your leg a push to help you over.
Be safe, don't hurt yourself.
LoL wow :P All I can think about is how dirty that can be, stairs...:/
ha ha! a little ocd or maybe a virgo?
