A Basic Cadet did that to himself on purpose the summer I worked BCT... his parents wouldn't let him come home if he just quit, but would still accept him if he was "injured" and medically turned back. Kid slammed his head on the wall/floor until he got a concussion and walked around with a huge grin on his face until the day he outprocessed.
Oh memories...
But they seriously banned situps in the hall?
That's what I was told by a BCT1 flight commander within the last month. Probably need to put padding and safety rails under the pullup bars in the stairwells just in case someone might twist an ankle and fall down the stairs.
but, somehow, they will survive - this may be another thing that goes in the "back when it was hard" pile after they graduate.
