I read an article saying that one should place his feet wider in the squat stance so that it forces more work on your hamstrings, which can lift more weight. I was wondering if this means you can place your feet as wide as you would like to. I am flexible from my days in martial arts, and my squat stance is more like a sumo squat. I was wondering if squatting very wide is a form of 'cheating' or is this just a matter of preference? It felt easier to do the squat because a wide stance makes you squat down quicker than you would in a regular stance. Also, after you squat all the way down, do you rise and lock your legs after each rep just like you're normally standing?
