I've seen no Smith Machine that takes into account the anatomy of each user and accomodates their particular groove in a lift. There is certainly increased chance of injury with a SM as opposed to the opposite, which its proponents would argue.
Well, sure. It is not designed for that purpose. I do not believe there to be any evidence of an increased risk of injury with the Smith nor do I think that, done correctly, there is any logical reason for the increased risk of injury. As Kunk and I point out, it is a limited piece of equipment that can be quite useful when training alone. I do not use the Smith all the time and I do not use it for every thing, but it is a fine tool for the uses I do make of it.
If your grievance is that it is overused or even sometimes used incorrectly, I would grant you that in a heart beat.
