I have a couple exceptions to this rule. The first is if you are a professional body builder and you make your living by going on stage to show off the results of your hard work. My second exception for when it is okay to get into flexing is if you can beat the crap out of me. Then by all means do what you want and know you have my full support and admiration. Unless someone fits into the two above mentioned categories, I will be more critical of them since they probably do so for attention or because they think a lot of themselves.There are many different flexing poses to choose from. Of all these different poses, the worst one has to be the Hans and Frans front pose with your hands gripped in front of you like an angry gorilla. If you are going to go to the trouble of performing a muscle pose I suggest you go straight to the coolest one in the book. The "Captain of the Universe/To infinity and beyond" pose as demonstrated by Arnold below. No, that is not me and I'm sick and tired of people always confusing my body with his. I'm afraid If I ever attempted this pose, that lasers would shoot out of my fingers and I'd turn into an intergalactic beacon of coolness.
