Body structure is a factor right. So should one try to fix his squat execution, just do a different squat, or should work on some parts to balance/strengthen their body.
Of course, it is. In everything we do.
What I was trying to explain to you via twitter is I need context. You haven’t provided me with proper context, video or an example of anything specific i.e. limitations,, build etc. With that said this is a question that I cannot answer. I need to watch the person lift, see what levers were are working with then decide for the person. There are many variants of the big lifts that can work for people with limitations that don’t want to compete.
Please resubmit with specifics, who you are talking about and some video please.
