To all of those of you who deep squat, especially those who have squatted deep and heavy for a long time, do you have any knee problems?
How long have you squatted and how much do you squat? How have squats affected you?
I just want some anecdotal evidence to present to the local gym rats. I'm sick of them telling me not to go so deep - "90 degrees is best, otherwise you'll get arthritis and osteoporosis.
Also to the scientists among you, are there any article/journal references that also provide such evidence?
Thank you for your time.
ps I need as much stuff as possible, anecdotes and references.
