Hi Lisa,
I'm not Cathe but I think I remember reading in earlier posts that you can start STS right away. You would probably want to take your 1 week recovery week as you did between mesocycles but you should be good to go after that. I'm in my second rotation of STS and I actually took about a month off in between. Just did some different workouts. I'm using the same weights for most of the exercises and truth be told, I think it's harder the 2nd time around. What a great program.
