The Polar Loop records data from your activity – be it walking, cycling or making a cup of tea – all based on the level of intensity – high, medium, or low. The device then allows you to view you days, weeks or months online so you can see when you’re more active, and when you’re slacking.

You can link up with MyFitnessPal to track the calories you burn vs those you consume, too – so if you’re monitoring your weight this could be helpful.

Data can be uploaded to the Polar Flow Web service, where you can also received tailored advice on where you could improve.

This one comes in at £79.00 from Polar. It won’t tell you much about your cycling performance, but it will give you info on your overall fitness and well-being.
