The personal trainer in your pocket, whipping us into shape on-screen wherever there's wifi, is a 2021 trend that's likely here to stay. And you're never fully dressed without a wearable fitness tracker - because even if you don't count your steps and monitor your heartrate, you should absolutely look as if you do.

In 2021 nobody said: 'I'll sleep when I'm dead.' In fact, how to sleep better was one of Google's most searched terms, as we all decided that shuteye was no longer for wimps.

Instead of an involuntary reaction to the last 45 minutes of your weekly all-teams Zoom, sleep became one of our most important and proactive pursuits.

Another function that once merited little scrutiny, this most essential action became an obsession.

For many, beset by the blues and anxieties of lockdown, exercise went from chore to soul nourishment.

A bike ride, run or even just a stroll within five kilometres became a mental health life raft. When the walls were closing in and the future was frightening, exercise was medicine, escape and solace.

Let's hope we continue to move for the right reason: because we love to.
