2. Choose the Right Style
Even if you swap shoulders regularly, you will still have a weight imbalance all the time which will mean your spine is not fully aligned, and muscles and ligaments can be damaged. Try to find a bag that distributes the weight better; a small backpack is best, but if you won’t wear one of these, try a messenger bag with a long and adjustable strap. This will allow you to spread the weight between your shoulder and the opposite hip.
