Check your movement quality every session. At the beginning and end. No, I'm not kidding.
When I used to teach personal training at a college in Australia, there was this stupid notion that certain exercises were for beginners and others for advanced clients. The fitness industry in Australia is as big a mess as it is anywhere else in the world, and the people setting the guidelines aren’t actually trainers of any decent level. Just like in most sports, the role of the administrators seems to only be protecting and rationalizing their jobs, rather than helping things improve.
