I'm thinking I'll start in the first week of March, too. I'm excited to preview, but I knew I wanted to take my time and do my 1 rep max tests over the course of a week or so, while I was previewing, and I just got my STS on Tuesday. Plus, I've been off my game with working out lately, so I need to rededicate and get back into my routine to be ready for the STS challenge!
