No I saw the video (it's still there for me) and looked it up as well so I know what they are and I even think I'll work them into my routine. I won't however drop barbell squats for a couple of reasons. One is I like them and at my level I know how to do them correctly (again I cannot and will not do a deep squat that puts a lot of pressure on my knees and spine). The other reason I like them is that because the weight is high as you it does require you to have a strong core to do them correctly but they also work your core as well. I do a fair bit of core work and this is part of it. I'm not worried about the safety of barbell squats, I do them weekly (5 sets) and have done so for years and I have never hurt myself doing them so I think I'm good. I do look for ways to add variety to my workout.

My previous comment was specifically for the video and how deep the person went in the squat...even without weight that would be problematic for me, even your comment about elbows touching the inside of the knee is too deep for me and causes knee pain. I do not subscribe to no pain no gain...more like no pain no pain...especially if the pain is joint pain...
