First, get the basics right that drive sleep:
✅Same bed and wake times
✅Morning sunlight
✅Move your body during the day
✅Wind down at night
✅Cool, dark room
If sleep tracking is making your sleep worse — ditch it.
Trackers are fine for bedtimes and routines.
They’re terrible for obsessing over REM, deep sleep, or “sleep scores”.
Wake up in the middle of the night?
Completely normal.
What backfires is lying there forcing sleep, clock-watching, or doing the maths on how many hours sleep you will get.
A lot of sleep problems aren’t really a sleep problem.
They’re a stress and overthinking problem.
Watching the clock.
Checking your sleep tracker.
Thinking, “I HAVE to fall asleep right now.”
Forget the conditioning sessions you see on Instagram or HYROX where people are absolutely killing themselves.
Take tips from the best athletes and runners in the world:
80% low intensity/20% higher intensity.
Building cardio is about frequency, not intensity.
How to know you’re in Zone 1
1️⃣ You can comfortably hold a conversation If you’re breathing hard, you’ve left the zone.
2️⃣ It feels like an embarrassing shuffle, not a run.
Most beginners jog VERY slowly — or walk — to stay aerobic.
Want to stay in the right zone?
Alternate jogging and walking.
OR maybe it's just a brisk hilly walk.
This stops your heart rate skyrocketing
and keeps you in Zone 1 like the pros.
But when you go too hard?
Your heart beats too fast to fill properly.
It pumps quickly but never fills fully,
so you don’t get that full stretch → contraction it needs.
And without that full stretch + squeeze
you miss the physiological changes that actually make you fitter.
When you go slow, your heart has time to fill up properly
(the muscle stretches).
Then it contracts and pumps a full chamber of blood out (the muscle squeezes).
Exactly like your muscles in the gym -do that again and again…
and your heart + aerobic system get stronger.
You don’t need to match their pace.
You need to match their heart rate zone.
When you go too hard, you miss the benefits of low-intensity work…
...the zone that actually builds your engine.
