Stay in the know and learn about your body and fitness levels with the Fitbit Inspire HR Fitness Tracker. It offers a huge range of features - track your calories, steps, distance travelled, daily activity levels, sleep patterns and more. The Inspire HR can automatically recognise the exercise you're doing from walking and running to cycling and then records it for you in the Fitbit app, so it's easy to look back over your week and check you're getting enough exercise. It's waterproof up to 50m.
