why would you want to do 250 bodyweight squats?
I'm cancelling my gym membership, since it is too crowded to get in a proper workout before having to head to work on most days, so I won't have access to a squat rack, yet I don't want my legs to atrophy significantly.
At that point you are doing cardio and there is a reason nobody does bodyweight squats as cardio.
What reason would that be?
Why not just get a couple of adjustable weight dumbells?
Try to predict something important in a way, that it will be easy to judge it in 2014, how (in)accurate your predictions really were. Don't leave too much space for a doubt what was really said.
