Good Sleep Trends
More: The Detailed WHOOP Review
The WHOOP app has just expanded the information it gives you on your sleep quality. The core premise is that whilst more sleep can be good, more GOOD sleep is definitely good.
Q: But What is GOOD sleep?
A: There’s is no fixed definition of GOOD sleep but WHOOP’s take is that it includes elements of consistency, restorative sleep, and time asleep
WHOOP now coaches your sleep in 4 new areas using these metrics
- Consistency is a major driver in illness prevention and is perhaps the most important component of ‘good’ sleep. WHOOP looks at how similar your sleep and wake times are
- Sleep efficiency is driven in part by circadian health and is considered in the context of the percentage of time you spend in bed asleep.
- Sleep debt considers the difference between the amount of actual sleep to the amount you need. As well as factoring on illness/injury prevention this has a role in brain function
- Restorative sleep consists of the DEEP and REM stages of sleep. These account for physical and mental restoration respectively and are together considered as a percentage of your overall sleep.
These 4 can then be reviewed in weekly, monthly, and 6 monthly Trends.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
