Katrin Tanja Davidsdottir Instagram – I like going hard! ✨😏💪🏼 rest. recover. REPEAT! One thing that helps me recover in between intervals the fastest is literally watching my heart rate while I focus on my breath .. I swear, it drops so much faster 🤣 watching it real time with my @whoop is like a little game to me! Get that HR as low as possible so I can go HARD again! Hope you guys crush it today!
