Three things. One is a lift brace which is specifically made for use on the job. You can find them online, Lowes or Home Depot. If not used correctly it will have an adverse affect and make your back weaker in the long run. It has suspenders and 2 closures. The first is like a cumber bun on a tux. Only secure it like a belt, not tight. The second involves 2 elastic bands, one on each side. When you get ready to lift pull those 2 tight and secure them in the front. Once you finish lifting loosen them. If you do not follow this procedure to use it correctly your back muscles will become weaker and dependent on the brace. Second, use your legs and not your back. If you have ever watched professional weight lifters they square their legs up under them before they lift. Third, do not bend your back when setting the weight down, use your legs and squat. This will be difficult at first until your legs become stronger. Also, because you have not been using your legs there will be some cramping for a couple of weeks, especially at night. Get some pediolyte popsicles and eat one twice a day to replace electrolytes in your body. Dill pickles, bananas and oranges are also helpful for a snack during your break at work.
