Gonna start off by saying, glad you dropped the 20 bucks for the book. Read it over and over and over until you understand it. I've been doing 531 for the last 18 months solid. The first 8 months were the easiest. I only had to reset my squat. Now my actual "training maxes" are well over my first real maxes. And its much more difficult. My endurance does suck though, as I don't do conditioning consistantly.. If you go to jim wendler .com (no spaces) and read all of his blog stuff, you'll have a better understanding of 531. It is alot, but its worth the read. He talks about how 531 should be done over the course of the year, which is incredibly interesting, among other things and answers q&a about his creation...the 531 program. Don't hesitate to ask Jim your questions. He definitely doesn't tell people what the want to hear only what they need to hear. Fun fact-tone has to do with sound, not muscle definition. Not sure who started the whole "tone" thing, but they are stupid. Oh yea...the bench press conundrum. The bench press is not a dedicated chest movement. You have to stabilize yourself on the bench with your feet, butt and upper back. You have to pull the bar out of the hooks (not press and rotate) with your lats. Then you have to stabilize the weighted bar with your back, shoulders, biceps and forearms. Lower the bar with your lats to your sternum area (lower chest) with a slight tuck in the elbows (read your elbows are not straight out unless you want ****ed up shoulders, also a reason to ditch flyes). Once you touch your chest, press the bar up by driving yourself into the bench with your feet. I think someone mentioned Dave Tate's 6 week bench cure on youtube. Watch it.
