Unfortunately once people have had instruction from a trainer they are often then on there own. I cant be with my clients everytime they are in the gym. If you show someone how to do something there is no gurantee that they will remember its human nature.
If it was a fact that a smith machine was of no use for gym users then why would gyms buy them and why would they have been invented?
