Ah ok fair enough. I didn't mean anything offensive , so if it came out that way I apologize. I think we are on the same page with this. My stance is, and always has been, you can't make blanket statements like "no one doing non-competition lifting should need a spotter," or "if you need a spotter, you're lifting too much," as was implied by other posters, any more than you can say "everyone needs a spotter all the time on every lift." I've said this before, but it bears repeating- fitness is not a one size fits all endeavor. I will say this though- while there exists no such study as you mentioned, I think it is safe to infer from the two links I provided that both of those members of the clinical field feel like spotters are being severely under utilized, or they wouldn't have mentioned the ACSM's stance on the topic. Including that info in an article about weightlifting injuries seems like a pretty straight forward indicator of the stance of at least part of the medical community.
