This Fitbit Inspire 3 smart watch is like having your own personal trainer on your wrist. All your activities and stats for the day are displayed clearly on its sharp AMOLED screen, while the durable aluminium case can stand up to even the most rigorous routines. It’ll even track your heart rate and how many calories you’ve burnt – useful stuff for exercise enthusiasts. It’s also waterproof up to a depth of 50 metres if you fancy cooling off with a dip after your gym sesh. And when you’re heading to bed, you’ll wake up to a full rundown of your sleep pattern, so you know how much rest you’re getting.
