In this video, I discuss the topic of recovery and the significance of tracking data using devices like Whoop. I explain how Whoop measures heart rate variability, which indicates the responsiveness of the nervous system to stress. I also highlight the impact of stress on heart rate variability and overall recovery. Through personal experience, I share how making significant changes in my lifestyle positively affected my health, including improvements in sleep, training, and resting heart rate. I emphasize the importance of recognizing and addressing stress in our lives and the value of tracking data to make informed choices.
