People Vs Fitness— This Is Going To Hurt To Watch!

Why do I laugh every time other people fail...  I almost feel a little bad about it.  But don't you feel bad today....because this video is hilarious!

First thing I would like to say is I hope all these people are ok.  So please don't think I am some heartless guy who enjoys other peoples pain... Well I do slightly... Does that make me a bad person?
