Exercise though, has to be something you enjoy.
It’s no good taking out a gym membership if you don’t really like that sort of thing.
This is why the gyms are full the first week in January and then become considerably less so, as the weeks pass.
That promise you made to yourself to spend an hour in the gym every evening after work, suddenly becomes less attractive a couple of weeks in to a new year.
Maybe golf or cycling is your thing. Or walking.
