Mountain biking is great for weight loss because not only do you get an awesome leg and cardio workout, but you also lose two pounds of liquid every time you pee on yourself because a FREAKING BEAR COMES OUT AND STARTS CHARGING YOU.
Yes, apparently that's a terrifying thing that can happen.
YouTuber Dusan Vinžík was following his friend down the mountain when an enormous brown bear appeared and started to charge after his friend.
