There are some things that need clarification, first of all, not all bridge bastions spawn like this, there are two areas, the right rampart, and the left rampart, and both areas could be a triple chest (which is the one in the video) or a single chest or some combination of both. Basically, the bastion in the video is not likely to be the same bastion that you may encounter in a run.
Also, make sure to craft a golden helmet, I had a golden helmet in the video by default, but if you don't, craft a golden helmet or else you will die (speaking from experience).
Last but not least, if you are just getting into speedrunning, do this on version 1.16.1, no brutes spawn in 1.16.1. If you're going to do this in any other version after 1.16.1, you may need to alter the original route.
