Which form of exercise do you actually stick with through a British winter?

A reliable indoor option that works whatever the weather, though the changing rooms and £6 entry fees can test your commitment.

A community staple that gets you out the door even when it's bucketing down, with the promise of a coffee and a cake afterwards.

Cheap, convenient and weather-proof, but requires the discipline to actually press play instead of scrolling through Netflix.

The social side keeps you turning up on freezing Tuesday evenings, even when your hamstrings are begging you not to.

The lowest barrier to entry of the lot — the dog doesn't care that it's raining sideways, and somehow neither do you.
