In addition, ribs forward, shoulders depressed(think heavy coat bringing your shoulders/shoulder blades down and back, tucking your shoulder blades into your "back pockets"), low back arched/tight(think about your ass tucked and away from you), pressure on the heels, wrists rolled forward/elbows tucked(based on your flexibility this will differ, but think "elbows under the bar" while still tight in the mid-shoulder blades. Again, don't go by what you see but how it "feels": pull the bar apart while trying to bring it down around your body; it shouldn't, but imagine), neck packed, big breath in through the nose before the lift, hold it on the ecncentric, and forceful exhalation through the mouth on the concentric. Seems a bit much but you'll realize this is all natural once you get it down. Practice and perfect. Good luck.
