I don't believe that they necessarily are. I mean, any exercise can be detrimental, but generally (not always) that can be narrowed down to user error. I think if they are sparse in your normal routine and your training them heavy, its asking for injury. Just like it would be with any exercise, regardless of how easy it may seem with lower weights.
