yeah i never used my locker in secondary school, carried all my textbooks and schoolwork in my backpack. i remember feeling weird walking around without the weight of it sometimes
Current tension related to pull ups and computer time, I believe
I think backpacks weren't heavy until HS. I often single shouldered them. We had lockers (HS), so it was to school an back mostly. Also I wrestled all 4 yrs, so good back shoulder strength
TRYING THIS - https://counterstrain.com/3d-counterstrain/how-it-works/… where chiro/massage failed - I need 9 sessions to fix all that fascial "damage" but she is optimistic in my case ALSO get a custom-fit REI backpack that distributes weight on your waist.
This is actually the BIGGEST thing holding me back from greatness, and honestly it's fucking silly, I'm so jealous of GenZ that they don't have to wear heavy backpacks (tho they prolly still do b/c K12 doesn't make online textbooks easy)
