In a little continuation of the "backpain" post, do any of you wear back support or weight belts when you are working? Do you wear a wide belt or thin belt; leather or softer material? Any comments on your experience would be appreciated. A guy at work gave me a 4" leather weightlifting belt, and it seems to help support the lower back when lifting. Some people said that I should have a "wider" belt? Thanks for your input!
