Lol - from memory it went something like this;
PT - "Any reason you use a stance like that (> shoulder width, toes pointed out)
Me - "If i go any narrower than this my chest caves in, i lose the arch in my back and struggle to hit depth with good form"
PT - "Hmm you might need to work on your flexibility a bit then, you could give yourself some joint problems in later life squatting like that"
Me - "I've been working on it for a few months and whilst my forms improved, i still feel more comfortable in this stance. I put it down to being long limbed amongst other things"
PT - "In that case you might have some muscle imbalances then (proceeds to point to his soleus/gastrocs/glutes"
Me - "Ah ok, i'll think about playing around with it later"
Must've come straight out of his Premier (or whatever other bunk qualifications there are) training book, i'm surprised i wasn't told the bar was too low on my back too!
