It may seem like obvious that you use safeties when squatting but even those who use them sometimes don't use them always or don't always set them properly, for example not too low. There's also safety catches made for bench pressing. Who uses them? Almost no one. But then you use a spotter right? A spotter can do jackshit if you suddenly lose control, there is no time to react, you can catch the bar with your forehead or throat. Things can go very wrong sometimes even if you aren't a complete retard. I didn't watch the video but trying for a 25lbs PR with a spotter doesn't necessarily mean outrageous stupidity necessarily imo. That's something many or most have done at some time in their lifting career. I don't do it actually but then again I set up my own safety catches for example for the angled leg press if none are built in, even if using very submaximal weights. You never know if you might suddenly tear something or even lose conciousness or someone bumps into your machine. That's one machine where things might go very sideways and you end up a cripple from the weight crushing you. 99.9 out of a 100 never thought about that with the angled leg press and many people use absolutely ridiculous weights, probably more than with any movement ever.
Some powerlifting orgs use those loops in the monolift that can catch the weight. Even with 5 spotters that's smart imo, spotters are absolutely useless if you need to dump it suddenly, it happens too quickly, but many purists don't like this idea at all, it doesn't look good I guess. They don't use them in the IPF though in later years the benches have to have safeties.
