Lunging is great for strengthening the mucles around the knee. The technique below is particularly effective with the use of dumbbells.
(It seems to help the "pecs" as well.)

Got a link? Google didn't help me. Sounds amazing.

Sorry.
His very intense Training Program was part of a one hour docu that his Wife did on him for the Fit TV's Series, "Insider Training" that aired last year.
You are in luck as it will air again next week...

And yes, the dude is fking amazing and is an example of what all around disciplined fitness really means.
Oh yeah, I can't even imagine how many MILLIONS of DEEP KNEE BENDS he's had to do for the past 40 years of surfing.
Go here and watch his videos.... http://www.lairdhamilton.com/

first, people must stop answering with black or white absolute answers, b/c the knees are more complex and there is a lot that isn't well understood.
you have the tibialfemoral interaction on the menisci, the loading of all the ligaments, loading of the quadriceps / patella tendons, and patellafemoral stress. anyone of these things could be considered "knee pain" and all are likely stressed in different kinematic & force combinations.
i'm trying to look over this review article I found on PubMed. it's pretty long but discusses various consequences to different loadings. in what they discuss it seems most experiments don't go past 90-100 degrees of knee flexion - that doesn't mean going past is bad, however.
in terms of shear stress, yes its true hamstring activation will help reduce stress (referring to crossfit thread), but that is only one element.
as the knee flexes in a squat, there is an increasing patellafemoral force. basically, put a piece of rope over your kneecap, and pull at both ends at different angles. if you pull away horizontally, there won't a force, but as you begin to pull down at more vertical angles, the compressive force will increase. so the compressive force between the patella and femur increase (at least up to 90 degrees flexion).
if the patella is not properly aligned, this can certainly lead to high stress / pain / cartilage degeneration. however, it is not clear if even lower knee angles increase the stress, because the torque demand at the knee may lower in deep positions (relative to 90 degrees).
squats (at variable depths and resistances) are not going to be good for everyone. people have different pre-existing conditions, relative segment lengths (think femur / tibia orientations), and patella mechanics. certain things may stress their knees more. obviously a great indicator is pain. if you are feeling knee pain when doing some time of squat, then stop doing it! if it feels okay, then might be fine to continue with.

People spend their entire professional lives learning how to teach and perform olympic lifts correctly, and crossfitters think they can take a 4 month online certification course and go out and teach them. It does not work that way. Also, the lynchpin in the entire crossfit olympic lifting communitty is Mark Rippitoe (spelling?). All of the college strength and conditioning coaches I have worked with find some flaws in his teaching/ideology; and he does not have a great reputation in the strength and conditioning community.

Don't care either way about your arguments since I wouldn't put much into anyone's bragging about how much they know, but what the hell does someone's income have to do with anything? I've skied with someone that made 8 figure incomes, but it doesn't mean I can ski worth a shit (he ain't so great, either)

I have experienced first hand a crossifit instructer teaching people how to do deadlifts, squats, and power cleans INCORRECTLY AND BLATENTLY FALSE.

Ed F wrote:It sounds like most of those things would result in knee pain eventually from almost any physical activity. I stand by my claim that a normal person with no injuries and no biomechanical problems should be able to perform full squats with weight with no issues. I think squatting gets a bad name (along with deads) because there is so much potential to hurt yourself if your form is bad. Honestly, the few times I've done "sissy squats" (to 90 degrees), I've really felt it in my knees.
