Who? In both powerlifting and strongman circles he is regarded pretty highly actually. I'm competed in both NAS (north american strongman) and IPF (international powerlifting federation) and the talk of people who actually compete is how much Ripp has done to bring real knowledge to the masses.

I've seen a few critiques of SS. One particular one was on how he recommends doing cleans, but in general I've found it to be well accepted. I do a variation of SS right now and I enjoy it.

It's popular so it's bound to have critics.

Mind expanding on that beyond just "Some people don't like this guy"?

I'm not sure why you're being voted down. I've also seen some criticism, especially with respect to older (+40) people causing serious injury to their vertebra with the loads from correctly performed lifting. Lifting weights is not for every body, no matter how well you follow directions.

Have you got links to those? I'd be interested to see them since I'm in that group. For me personally weight lifting seems to have prevented a lot of injuries that I used to get.
