I'm totally drinking the Kool-Aide! I love it! I've been at it for almost two years (with a couple of 3 month breaks due to some herniated disks that flare up from time to time) I'm finally getting to where I want to be. I'm at the Rx-ed weight on most workouts now. For me, that's a huge accomplishment, since I started out as an overweight, out-of-shape 37 yr old desk jockey.
My coach approached me the other day and asked if I wanted to become a trainer, so, we're working out the logistics on that and trying to schedule the Level I cert. now.
