WATCH: This ‘documentary’ on gym life is absolute perfection

Plain and simple: If you’ve ever gone to a gym, even once in your life, you will enjoy the NSFW video above.

The folks behind the Buff Dudes Channel on YouTube have made this "National Geographic" inspired "documentary" about gym "wildlife."

From the teenagers who hover around one machine while taking selfies to the guys looking to hit on women to the elderly gentlemen who don’t have any interest in covering up their naked bodies and much more, it’s all covered in the excellent parody.

Warning: If your New Year’s resolution is to join a gym and work out more, you might not want to watch the video.
