@jesusloverr So I have no idea about science background of warmups but I will speak nonetheless, just based on my own experiences.
I've been working out for two and a half year now. Mostly calisthenics but also with a free weight from time to time. At the beginning I was warming up for 15-20 minutes before every workout - it was at this time when I got my 2 major injuries, and yes - both of them during the warmup and not actual training.
The first time I sprained my wrist. This forced me to completely stop working out for 2 months and my wrist hurts to this day if I perform an uncontrolled move.
Second time something snapped in my shoulder. This yet again made me stop working out and hurts to this day, but only when I sleep, not during workouts.
Since the second injury I stopped warming up in general, and surprise surprise... not even a minor injury since then, and I'm in my peak performance ever. As I mentioned, I don't know a thing about science behind warmups, maybe I was doing it wrong, maybe I'm the type that shouldn't warm up at all, but what I know is that I probably won't ever warm up again.
