Lowering Resting Heart Rate Without "chronic Cardio"
I'm very interested in lowering my resting heart rate, given the correlation of a lower resting heart rate to greater longevity. However, I've also read about the drawbacks of "chronic cardio".
What's the optimal way to lower resting heart rate from a health perspective? It seems like it's probably HIIT but I wanted to confirm that before I dove in full-on.
