Personal trainers often focus on exercise form without understanding the principle that actually drives results: safely bringing clients close to muscular failure. Master the underlying principle, not just the technique, and you get better outcomes.
What I see happens 99% of the time with trainers, uh, the problem being is most trainers look at techniques rather than understanding the principle. Yes, that's on a surface level what you want to understand, but below the surface you want to understand the principle behind it. One of the principles behind it is to bring you as close to proximal failure as possible in a safe way. So you don't just want to understand techniques in everything, in all learning, you want to understand the principle behind the technique that gets the result.
