Honey I shrunk the fitness tracker

There are more health and fitness devices on the market than ever, with the tech to track everything from step count to stress levels.

And recently, the fitness tracker has downsized. Enter the Oura ring - Jenifer Anniston has one. And so do I. It comes in six metal finishes, and eight sizes.

Like Gollum I hungrily put it on. It's chunky but not overly so, and lightweight too.

Easy to set up with an app, the Oura ring is instantly able to track heart rate and activity levels, suggesting a base level of calorie burn. It automatically tracks any exercise including housework - and adds it onto a daily diary.
