Fitbit currently sells five activity tracker wristbands – the Fitbit
Flex 2, Alta, Alta HR, Charge 2, Surge and Blaze – and two clip-on activity trackers: Fitbit
Zip and One. That’s a confusing range, and there are rumours of a Fitbit smartwatch too now that the company no longer sells its Surge sports tracker.
Activity trackers can motivate you to exercise more or improve your sports and fitness regimes. Even moderate exercise can have a positive effect on your physical and mental health.
