The 4:45 Alarm Only Works If the 9pm One Does
Everyone who commits to early training in September commits to the alarm. Almost nobody commits to the other end of it, and that's why most of them have stopped by half term.
The 5:30 session is an evening decision, made at about half past eight the night before, when you decide whether to start another episode.
The arithmetic is unforgiving. If you need seven and a half hours — and most adults do, whatever they've convinced themselves about coping on six — and the alarm goes at 4:45, you need to be asleep by quarter past nine. Asleep, not getting into bed. Which means the wind-down starts at half eight, and the last coffee was at lunchtime, and the episode doesn't get started.
Unforgiving, and it doesn't get less true.
Take the alarm and not the sleep and you get the pattern I watch every autumn. Someone starts well in the second week of September, trains three or four times a week on six hours' sleep, feels good for a fortnight — then gets a cold, or tweaks something, or hits a Thursday where they cannot get up, and it unravels. The training was built on a foundation being withdrawn every night.
Sleep is where the adaptation happens. The session is the request; the strength gets built while you're unconscious. Cut that short and you're doing the hard part and skipping the payoff. Short sleep also makes you hungrier the next day, worse at food decisions, and worse to live with.
The wind-down takes about half an hour.
Caffeine has a half-life of five to six hours. A coffee at 3pm means half of it is still circulating at nine. Training at 5:30, make the cut-off midday and watch what happens to your first week.
Dim the lights from about half eight and use the blue light filter on your phone. Bright overhead light tells your body it's daytime.
Get the phone out of the bedroom. It's the most effective device ever built for turning a ten-minute wind-down into a fifty-minute one.
Go to bed at the same time on Friday and Saturday, within an hour. The weekend lie-in un-sets everything you built during the week, which is why Monday feels like jet lag. Physiologically, it is.
Four days before term. Set the 9pm alarm as well as the 4:45 one — literally, on your phone, tonight.
