Ok so I know this is probably laid out very clearly for most people, but I have a tendency of looking too closely at the details.
So anyway, I've been doing the WODs for a long time now, so I assume I won't have to start at week 1. So basically I find where in the weekly workouts I fit? For example I try week 1 and I can do it perfectly, move to week 2, 3, etc until I find my approximate level? Also what happens when you get to week 12?
Also how does HS1 integrate into this? Can you do F1 and HS1 workouts concurrently? Say I'm doing 5 FS1 workouts per week, how would I fit the HS1 workouts in?
