Fitbit Charge 6 Fitness Tracker - Obsidian Black, Black

Give your workout routine a serious boost with this Fitbit Charge 6 smart watch. When you jump on a treadmill for some cardio, it'll keep track of your heart rate and calories burnt, as well as your overall activity throughout the day. And when you want to check on your progress, the bright AMOLED screen clearly shows off just how far you've come, while its durable aluminium case keeps it safe from life's little accidents. You can even take it in the pool since it's waterproof up to 50 metres - perfect for a post-exercise swim. Plus, there's a sleep monitor too, if you fancy a look at how much rest you're getting every night.
