As we're doing plank jacks (um, yes, those are just what they sound like, upper body: plank pose, lower body: jumping jacks) :

"Keep it up, we're halfway there (my mind: Halfway!!! Only half-fricking-way???) And remember when it feels like you can't go on, when it's burning and hurts, those are the ones that count. That's when the real work happens."

Got. it.

I finished the workout and opened my Bible.
