There's a direct correlation between the beginning of the year and the number of gym memberships. During the first couple of weeks in January, if you walk past a "fitness centre", there's a good chance you'll see a bunch of people who're there to enroll.

YouTube channel Buff Dudes decided to make a hilarious video chronicling the happenings in a gym, and they shot it like those nature videos you see on Animal Planet.
