I’m 41 and my body is nicer to be in than when I was 25.
Like you, I have much less youthful buffer that shrugs off poor sleep or overindulgence, but I have much more knowledge and much better habits.
Daily habits: better nutrition (based on Bryan Johnson’s super veggie and nutty pudding), stretching, weak points warmup, proper oral hygiene, regular bedtime
Weekly habits: 4x gym, 3x run, 2x weighted walk
I have used ChatGPT to work out a program that is helping me to overcome injuries and niggles while building strength and cardio. I’m 3 months into my latest training schedule, and it’s unreasonably effective.
Reminder for anyone that doesn't know better: having good sleep is dependent on a few minor lifestyle adjustments. Like avoiding heavy (or any outside of fruit and vegetable) meals and exercise a few hours before going to bed. And avoiding caffeine after noon.
You don't need to be a health champion to have good sleep.
