who said they weren't?
however it doesn't mean they should be used. belts, straps, gloves, wraps, all that shit I am 100% against.. you use them and you won't develop your core, your wrists, and your forearms correctly. the guys who walk around the gym with a belt and wear gloves day in and day out i guarantee have horrendous lower back core strength and their grip is horrendous. i would like to see them lift without their belt and their gloves and see how they do. they would likely struggle bigtime
i'm not one of those guys at the gym who go around telling people this though.. if someone wants to bring the entire Dick's sporting goods section to the gym with them thats their business. however i have talked to countless guys who have come up to me while i was doing squats and deadlifts and have asked me "hey you don't wear a belt?" or "you want to borrow my belt?" .. and i have told them why I don't wear one... so i hope i have explained it to everyone in this thread why a belt should not be used.. if you want to continue wearing one and crippling your lower back core strength then thats your own business, just remember long term its gonna hurt you more than help.
