Автор описывает методику повышения личной эффективности, основанную на так называемой "адской неделе", практикуемой у военных (время особо трудных нагрузок и испытаний). Речь идет о том, как нечто подобное провернуть в обычной жизни. Автор советует, в какой период лучше провести опыт с адской неделей.
If you’re an athlete, then this may be a week incorporated into your training plan, when you intend to “train down”, as they say. I know rowers have a period like that before important championships, when they produce an artificial performance peak by reducing the exercise workload for a specific period prior to taking part in competition. Among other things, this involves a period of several days when training intensity is built up, followed by a short period of “unloading” – reduced workload – immediately before a race. If you have a more normal job, you should perhaps choose a week you know will be demanding at the outset, so that you have a challenging task to face in your Hell Week.
Подскажите, пожалуйста, как в этом контексте перевести фразу train down.
