As I understand your recommendation is to perform hack squat / leg press with a relatively wide stand, feet as low as possible and toes pointing out. I assume this is to maximize knee flection. Having done some olympic weightlifting many years ago, it feels quite natural to me, and likely stronger if compared to a narrow stand.
Would you recommend keeping this foot placement for every movement (squat / hack / press) or there is any point in using a narrower stand (feet straight and relatively close) for some of these movements? Like for example wider for the hack and then move to closer for a leg press in the same session?
There is a lot of talking about “targeting” an area with respect to the other and I wonder whether this may be true BUT something that would be useful only for pro athletes with massive quads, having to work on “refinements” (but not so critical for the general pop).
