We've all seen a firetruck make its way to a fire, but have you ever thought of what firefighters go through when they train for such a job? Chances are this video will make you extremely uncomfortable.

I had to shut it off once the recruit got stuck, around 1:26. I'm not sure if all departments use this training, but the video popped up on Reddit and shows a clip from "A Firefighter's Journey," it's pretty intense.

Take a trip through the "worm tube" with this recruit. Could you do it?
