Quantifying Fitness

A Data-Driven Approach to Fitness Training

May 31, 2023 - Willem L. Middelkoop

This Monday I completed 235KM on my fixed gear bike during the Fietselfstedentocht 2023. It was a nice ride with fair weather and favourable wind conditions.

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.

... as a trained cyclist this ride data is not good: heart rate of 180BPM at an average speed of 22KM/h - this is 'the COVID effect' on my body - MISERABLE DELUXE

My (early morning) resting heart rate is going down, too! It inversely correlates with my HRV going up. Some nights dip into the low 50's, high 40's - I am getting back into shape!

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!

Even my average heart rate during the day, including all my tasks as modern dad, is going down as my heart (and cardiovascular system) is regaining efficiency
