Shank, Great question. After working one-on-one with Sebatian Burns from Metal Milita, I and my team have changed our bench style for Westside to Metal Milita(where is where the setup comes from). Being up on our toes serves a couple a purposes. First of all, it allows us to get our feet way behind us and allows our pelvis to rotate down toward the bench (note the hips in the picture). This guarantees that my butt does not come off the bench and I get “red lighted”. Secondly, allowing my hips to rotate down allows me to get into a good arch and helps push my abs out, thereby shortening the distance I have to bring the bar down to get it to touch. Also, I’m able to push my heels toward the floor and, by doing this, I expand my midsection even further to shorten the bar travel. Don’t get me wrong, Westside technique is good but we are getting good results with the Metal Milita setup. My previous gym 1RM was 335lbs.
