The way you carry your bag each day might be doing more to your spine than you might think.
Carrying a heavy bag on the same shoulder every single day creates a consistent, one-sided pull that can gradually shift your posture out of its natural alignment. Switching sides throughout the day, or choosing a two-strap option, spreads that load more evenly.
Small changes like this add up more than most people expect.
If something is bugging you and will not go away, stop by. In addition to a treatment I’ve got real good strengthening exercises for the upper back and shoulders.
