I'm not sure what it's called, but the one where you have to lean forward to get to the bag of chips or the remote on the coffee table. Man those kick my ass. Twenty or thirty handfulls of butter popcorn leaves me winded for a week!
deads are killer but what always does it for me isnt one your pole and that is clean & jerks. They flat tear me up. And are always good for a shock to the muscles.
For me, it comes down to which exercise enables me to lift the most weight. My squat is 375 lbs and my deadlift is 600 lbs. I think the more weight your moving the more anabolic the exercise.
