Show Notes

From smartwatches to fitness trackers, more of us than ever are monitoring our health in real time. With just a glance at our wrist, we can check our step count, sleep quality, heart rate and, more recently, something called HRV.

But what do these numbers actually mean? And more importantly, how can we use them to improve our lives?

I’m joined by Dr Malcolm Finlay to break down the data behind the devices. He explains how to turn confusing metrics into meaningful action. helping you adjust your training, manage stress, and make smarter decisions for your health.
