Backpacks
Backpacks not only cause muscle strain and fatigue, but when used frequently, can also lead to bad posture and slouching. To avoid back pain, you should use a backpack with wide padded straps and a padded back. The straps should be firmly tightened, holding the pack two inches above your waist. When packing your backpack, make sure everything is arranged neatly and keep heavier items closer to your back. If you must carry heavy weights, consider purchasing a backpack with wheels or using a hip strap.
