This may be BS but I’ve heard that one exercise that the SEALS have to do is sit in a room all day in swim shorts and no heat and complete exercises at a desk. There are no bathroom breaks, no time outs no leaving your desk. If you have to go you have to do it in your shorts.
BFD. I can do that, and have, by accident, without being a SEAL.
I think we all did the first couple of years of life.
