At these hard financial times when everyone is looking for ways to cut back on their budgets and save, we ask ourselves if each purchase is a necessary purchase or not. If you are just starting to exercise and are needing some weights to lift, try filling a couple of plastic milk cartons with water and use them as your weights. You can also use canned goods as your weights. An arm strengthening exercise would be to lift the carton to shoulder height then lower back down to thigh position. Repeat the exercise about ten times. Increase as your doctor advises.
