Backpacks are available in all shapes and sizes. Most contain multiple storage spaces for books, notebooks, pens, cell phones, or water bottles. Compared to a shoulder-style bag, the backpack provides the best choice for carrying materials between school and home. Why? Because the body's strongest muscles - the back and abs - support the weight evenly. However, if the backpack isn't worn correctly, the weight of the pack causes additional strain to the body.
