A negative can be addressed with almost any motion or exercise, This is the purpose of utilizing good form & movement postures. Speaking from experience on this one I will share w/u:
I usually squat heavy & utilize a variety of them @ varying weight. Box’s go over 500+ lbs., full squats – bar no smith machine 360+, deep’s & partials get a variety depending on how I feel that day.
Thinking back I have come in contact w/much info relating to bio-mechanics & physical conditioning, I cannot remember EVER finding info against squatting UNLESS there were some pre-existing medical issue.
Range of motion & control will vary from person to person. Easily coach able 1 on 1, not so much in a group. Remember your hips & core are your control mechanisms. If the movement is choppy & not to your standard stop them & reinforce what u want 2 see from them.
Weight used is primary concern in a healthy individual, start by assessing body control in a assisted deep squat for ur peace of mind. Lack of control, general bad form & over ambitious weight is what I see affect negatively more time than not. BUT, screw 1 of those up enough…
u will have all the negative issue 1 can handle
