The typical experience is for a coach of some sort to give you an exercise to do. He shows proper form and then has you perform. Typically he/she pushes you to an unpleasant level so that you don’t come back (I failed P.E. twice in college and had to get a waiver to graduate without it). That is normal.
Another usual thing is to so insist on correct form that you continually feel like a failure ready for a before ad. What I have found is that when I start a new exercise I find very difficult to achieve good form in, I need to just keep at it. Eventually, my muscles grow to meet the challenge, my body flexes to accommodate the moves and postures, and within a reasonable time I am doing the exercise in good form.
Try it.
examples are swiss ball side planks, pull-ups, swiss ball pikes and others.

Not sure how valuable is “good form.” When I was learning trumpet, it was pounded into my head (figuratively), “Never puff out your cheeks!” But I’ve seen many videos of famous trumpet players doing just that. And violin teachers insist you _must_ keep your hand and forearm in a straight line. Violin players aren’t always compliant.
IF tones were as important as Chinese teachers claim, Chinese people would never understand the lyrics of their own music.
