Skillin was very patient with you in your other thread about workout length, but since you've decided to post all your questions here as they pop into your head, I'll save us all some time and direct to you the "Before you post, read this" instructions for this forum that you obviously, ironically, did not read.
Before you post: READ THIS
I do this like Adam, not to reprimand you but to save us all a lot of time. One of the reasons Starting Strength has become popular is because it is a well reasoned and effective way to get people strong, and it works every time it's implemented properly. Our job here isn't to repeat the information we've already provided in a plethora of books, articles, and videos on the topics, every time a new person starts the program and doesn't bother to read or watch any of those things first. We're volunteering to help those who have done their homework and are struggling to implement or understand.
So we need you to do your homework first, and then we'll be happy to help you.
