I walk my 3 mile commute to and from work every day (with the occasional sprint thrown in, when I feel like it). I need to bring my work clothes and handbag with me, so have a backpack which unfortunately on occasion weighs up to 6kg (13lb). I’ve been doing this for a couple of years, and on the rare occasion I do this with nothing to carry, I have back pain. I’ve also noticed my general posture is somewhat leaning forward, I suspect being used to compensating for the backpack? My backpack has 2 should straps and a waist strap, but no chest strap, perhaps that’s the problem.
This has got me wondering how we should carry heavy things? We must be designed to carry (as well as lift) far heavier things over much greater distances, without the help of backpack. Perhaps shoulders/ waists are the wrong places to support this weight?
Am I missing a paleo way to carry my things to work?
