i have recently discovered just how unfit i am. apparently just because i can work for long periods of time and cope on minimal sleep does not mean i am fit. is it possible that my body pretends to be fit at work? i walk for hours on end, lift heavy things and constantly exceed my own expectations. and yet 25 sit-ups in a row is a genuine struggle. maybe im doing sit-ups wrong. hehe. well if only that were the reason.
