Short clips of correct form?

I’ve managed to pick up some good form cues from various trainers piece by piece, but I can’t remember which workouts had the cues in them, and many workouts just state where to place feet, sometimes cues like ‘bring them back to reach your pockets’.

Are there any FB resources on correct form for the most popular/ frequent exercises? I’m thinking body positioning throughout, and where you should feel the burn (and if you don’t, how to correct - like tick the pelvis etc).

I remember seeing a comment about some YouTube shorts and Instagram shorts but I can’t find them among all the videos.
