Why 7–9 hours beats any supplement on the shelf — and how to actually get it.
You can have a perfect program and a dialled-in diet, but if you're sleeping five hours a night you're leaving most of your results on the table. Sleep is when the work you put in actually turns into progress.
What sleep does for your training
During deep sleep your body releases growth hormone, repairs muscle tissue and restocks energy. Skimp on it and strength drops, recovery slows, hunger hormones swing toward overeating, and your motivation to train quietly disappears.
Get more of it
Aim for seven to nine hours and keep a consistent wake time, even on weekends. Get the screens out of your face in the last 30 minutes before bed. Keep the room cool and dark, and stop caffeine eight hours before you sleep — that afternoon coffee lingers longer than you think.
The takeaway
No supplement comes close to the effect of a solid night's sleep. Treat your bedtime with the same seriousness as your training, and everything else — strength, recovery, mood, appetite — gets easier.
