Whether you’re a full-on fitness fanatic or you just want to get that circulation going and shed a few pounds, activity trackers are the perfect accessory for keeping tabs on your exercise. Typically worn on the wrist, they can measure a myriad of metrics, such as distance, calories burned, and in many cases heart rate too. PriceRunner has rounded up deals on a stylish selection of men’s, women’s, and unisex activity trackers to suit a variety of purposes and budgets. Whilst most are equipped with a heart monitor, today’s premium activity trackers come loaded with fancy fitness-related features, such as GPS technology, distance trackers and connectivity to your mobile phone.
