Are you talking about the workout or the warmup/strength portion? I'll assume the latter, but all I can say is that is what they told me to do. I think the reason might be in that we really had gone over squat clean form since the on-ramp class and they wanted us to re-familiarize ourselves with the movement.
If you are talking about the workout, it's because my front rack sucks. It's just been in the past month that I've felt comfortable with any sort of weight in the front rack. The 105# I did for the workout was hard enough considering every thing else. I'd guess the RX'd weight of 145# would be close to my 1-3 rep max.
