Funny workout video from gyms

Most gym days are pretty uneventful. You get in, get out, and repeat. But then some days you see someone doing something that makes you say, "WTF?!" On days when you're just not feeling the gym, just think that you might catch one of these people, and it's sure to motivate your butt off the couch. Note that the language in some of these videos makes them NSFW.
