Hell week means a gruelling 120 hours of non-stop physical
exertion both on land and in water, with trainees allowed three
hours of sleep only on the third day. Only the best will make
it.
You will be surprised at what you can do at the end of it. Its a
very tough test on your mental endurance, because your mind will be
the only source of energy to keep your body moving during then.
Good luck
