My HRV measurements going down... as result from lack of training during my family's move from the city to country side

The morning after WHOOP calculates the readiness of my body to take on (new) training strain - you can clearly see my body didn't recover overnight: just a 7% recovery score!

I have gained weight as I lost fitness: confirming that WHOOP is on to something: there seems to be an inverse correlation between my weight and HRV trends

Training on a non-electric cargo bike! The kids love it! No need for fancy GARMIN head units: WHOOP can track your workouts on any vehicle.
