Awesome Workout Or Horrible Fail? [VIDEO+POLL]

Who goes to the gym? I have to admit, I cannot answer with yes. In fact, my idea of exercise is walking to and from my car at a rapid rate of speed. Trust me, with man boobs like mine, I know I need to get in shape sooner rather than later. 

So I guess I need to get my ducks in a row before I sign up for a fresh membership. What do I mean by 'ducks in a row' you ask? Well, i need to know what I should do when I walk into that magical place with all of the heavy round cylinder things. Do I stick to situps and pushups or should I go hard like this guy?

Seriously, what was that? Is that exercise even allowed? Is that even an exercise?
