Not defending Mr Rippetoe, never heard of him before. Mr Rippertoe reminds me of some of the football coaches I have met. Guess not too many guy's here have played sports because they seen so surprised or offended by his style. Sometimes a coach like him takes the first learning session to the extreme, coming down like a ton of bricks. Probably to establish his authority or territory like a dog pissing on a tree. Seen this over and over in coaching. The second, and following sessions, are much milder and that's where the real learning starts. But than again, some coaches have a hard time with teaching on any level. Why are the bad one's still coaching, I do not know. The video's showed bad habits to avoid rather than good lifting style. Who knows, maybe that was Mr. Rippetoe's idea in the first session. Highlighting mistakes and all that.
Agree with MisterMagoo, for the most part. Might add that when lifting from the DL or squat position you may want to keep looking upwards, rather than down or straight ahead. The body will usually follow the the eyes. Do not want to look down when lifting. That is where you have been. You want to look up to see where you want to go.
One of the Mod's seems to have some disagreement, or dislike, with me. Sure if we set down over a couple of beers we could resolve the problem. Been called a lot of names in the past, nothing to be bothered with. My favorite is when an opposing player called me a Polynesian N (the N word), which got me laughing so much I almost forgot to line up for the next play. Told one of my Samoan bro's that on the side line and he cracked up. Funny thing is that the offensive lineman pronounced it pooo-lee-knee-some. And this brother was black. No malice to anyone here. Good Luck.
