They just weren't ready. The physical bar is real, but it isn't what decides who stays. What decides it is what happens when the body stops being the hard part — cold, sleep-deprived, no end time in sight, and the standard doesn't care how you feel about it.
That's not a fitness problem. Every program in this space optimizes the wrong variable. They'll get you strong. They won't get you ready.
