I’m trying to improve my heart health and blood pressure, after a recent wellness checkup. I read about the Norwegian 4x4 protocol (https://x.com/fmfclips/status/1732227863628136614?s=12&t=WhYukSauChV1qH3L8ayoJw), did that on Saturday and plan to continue. Any other tips?

4x4 protocol twice a week seems to be delivering improvements to VO2 Max.

Imho too much hard and too few slow. To increase VO2max you should be 60/70% of the workouts in zone2.
