You need to strengthen your core to avoid back pain.
My posture, my backpack
Lick my workout and my core
Magnesium glycinate helped me with my back pain, can't take it every day but intermittently it works for me, take for 2 days and pause 1-3 days or longer until i notice my back is kinda stiff and also helps me sleep especially when i have to switch from night shift
Is that sleeping position really so bad as long as you're relaxed and not stressing anything?
Maybe someone from the ultralight, EDC, or onebag communities may have some insight on lightening that tech bag. Heck, I’d even take a stab at it if you post contents somewhere and let me know.
Deadlifts do wonders for my back to the point that if i stop doing them, my back feels funny. Also one legged stair calf raises do wonders for my sore feet from standing all day.
Back when I worked HVAC in the 90's I carried a army green flight line bag. I built it over 10 years using several philosophies.
You can't carry everything, and less is more.
Carry what you need to diagnose 90-95% of issues you expect to run into.
Carry what you need to fix 40-80% of problems. (depends on field and variety of tools needed), if you did 2# correctly you should know exactly what you need to go get to finish the job.
evaluate everything based on cost to carry and possibility of use. Example I carried couple dozen crimp connectors. I didn't need then often, BUT they also cost nothing to carry with no weight and fitting in a tiny side pocket.
