Joe that is not correct. A full squat wouldn’t overload the top end of the squat because it’d be way too light. Its actually obvious why the partial wouldn’t improve if it is never stressed.
So you claim
Ok ill add more, but i know no one will ever change your mind on anything.
Full develops quads and glutes much more than quarter. More fibres to use for the little movement will mean stronger, it will just take a few weeks practice. Also, look at weightlifters. They can partial squat a hell of a lot, they do it everty time they jerk and that weight has to feel like nothing in the dip, and they dont do quaters.
