Wholesale on the internet rounds.
I agree with the statement about no exercise being safe. I just don't compare squats and goodmornings. I believe there simply is a bigger margin of danger in certain exercises regardless if you do them "right". I look at, for instance, upright rows with a barbell the same way. You can do them correctly and still screw up your shoulders and aphorisms, to me, are not as much a consideration as the individual and his or her particular set of circumstances.
So I should point out that I'm not disagreeing with GM's across the board but only as a corrective measure in a scenario of overactive lumbar erectors and underactive glutes and hams. I simply think, in that scenario there will have to already be a measure of correction before someone gets much out of the GM's. Regardless of how many people do them, I do feel that they seem to be recommended to way to general a training population. There of course are no exercises without dangers but there is a risk continuum and I don't think it's fair to lump everything together.
Yes, we'll have to agree to disagree
