'Westside' is not a program...It is a powerlifting gym in Columbus, Ohio.
If you want to familiarize yourself with Louie Simmons's training philosophy, you've got a lot of reading ahead of you. A solid place to start would be with Dave Tate's articles on this site, (particularly the Eight Keys series,) and everything at elitefts.
The only thing I would add is that if you are a novice or intermediate lifter, you may not need as much dynamic effort work (you may not benefit from any at all...) Joe Defranco discusses this in the 'Westside for Skinny Bastards' articles on this site.
Best of luck
