Why is SS coach Beau Bryant teaching a horiz back angle on low bar squat?
I saw this official SS video from 2016 on teaching squats to the elderly just now and was confused on two things:
1. Beau is teaching a horiz back angle coming out of the squat. Look at 2:09. ouch! Back angle is supposed to be constant in the lower 2/3 of the squat (with a slight allowance of going a little more horiz). This looks nothing like what is described in SS and in Mark's videos teaching the low bar squat. And Beau is teaching what Figure 2-22 (and 2-42) expressly says you should NOT do.
2. He instructs the gentleman to do "thumbs around" at 4:22, yet the book (and other videos) are clear that it's thumbs over.
So the obvious question is why the deviations from what the book teaches?
Also, it was amusing how the guy sitting on the bench literally vanished into thin air at 2:18. That's a great trick :)
