Samsung is no stranger to the fitness tracking bandwagon, and as with the Galaxy S5, the Gear 2 has a heart rate sensor on its rear.

Apart from checking how nervous are, recording your heart rate can be a useful addition to your training arsenal as it can help you see whether or not you need to increase or decrease your effort levels.

You can choose to automatically track your heart rate while logging your runs, walks and cycles in the built-in exercise app, or you can use the dedicated heart rate app to check it manually.

The good news is that when it works it produces very accurate results. The bad news is that it doesn’t always work. Too often we found ourselves having to adjust the position of the Gear 2 slightly and take multiple measurements.

We'd recommend strapping the Gear 2 a little tighter to your wrist before logging a workout to ensure that it has sufficient contact with your skin to measure your heart rate.

The Gear 2 also doubles up as a pedometer and it works as well as any wrist-based step tracker we've used. But as is the case with its peers, it's not perfect. We got into our car with zero steps on the clock and after a 15-minute drive, the Gear 2 registered 17 steps.

Of course wrist movements and false steps plague all fitness bands, and in the grand scheme of things, a few hundred false step counts aren’t going to make much difference in the ten thousand or so we all take each day.

The Gear 2 naturally integrates all of this exercise, step and heart rate data into Samsung's own S Health app, which lets you analyse your stats in addition to logging calories on your connected device.
