Re: Weight belts again
If you understand why and how to use the belt properly, they will be beneficial. By this, I mean...when breathing, think "get fat" push your belly against the belt.
If on the other hand you consider the belt something magical, and thus pay little attention to your form, or breathing when lifting; then it won't matter.
If, you suck in your stomach before the lift, and the belt loosens, then the belt is not beneficial.
