I was pausing more, but I was told I was staying on the box too long. This video probably isn't the best representation, as I felt incredibly slow on this particular day.
I'll post some next week from my next box squat session.
Looks like a great place to train you have there. You're up in Maryland, right? My gym is currently catering specifically to CF, but we're looking at a bigger box, and I'm hoping to bring in a good deal more equipment eventually (racks, bands, chains, SM stuff, etc..). I bet those strict overheads with chains would fit nicely into my programming before too long.
