A lot of handlers at my hub have them. My back has been sore before at my old job but it healed and I never had surgery yet, thank God. If I get a lower back belt will it help prevent an injury? I read an article that if you've never had surgery it could possibly weaken the back muscles. OBVIOUSLY if I do get the belt that does not mean I should heavy boxes the wrong way. I'm still going to lift the correct way by bending my knees, back straight, avoid all pressure in your back. etc.
