I have good flexibility, don't need to get the bag off to grab things in it (and anyway, not like I'm taking out the laptop or my gym clothes more than 2-3 times a day). Stuff I need access to quickly is in my pockets. That includes my phone, wallet and keys.
And yes, I do a lot of vehicule ingress/egress (what a fancy way of saying it), it's just my vehicule well adapted to backpacks being on my back. 😉
Like I said, you're not accessing the bag's contents too often. Backpack's fine for that.
I'm trying to cover getting in and out of cars, trucks, boats, aircraft and armored vehicles while working around them. Do you have a better term?
My back musculature is just fine, 5 days of gym makes darn sure of that. My straps are also fine, went through quite a number of shoulder type bags. The NorthFace backpack just fits right, sits high on the back and hardly feels like it's there at all.
It was a joke, son.
There's just no real support holding the bag in place on a shoulder bag. It will move around. And it will put all the weight on one side of your body.
That's the entire point - to be able to bring the bag easily around front.
Once the bag's slung, it should stay in the back and most of the weight should be across the chest.
Also, next time you bend over to pick up something, try bending at the knee.
😉
All those are again mostly triceps/pectorals as far as push ups go. Haven't talked to a Kinesologist in quite a while have you ? 😉
You keep coming back to this like I'm making a serious statement.
Really, if you want to target the shoulders, hit the free weights.
As much as I can lift at the gym, moving to a lightweight backpack and a MBA instead of a Pro did wonders for me. Carrying around stuff is not a weight lifting competition.
Meh. On and off, I'll be required to carry 25-35kg over terrain where there's no motorized transportation available. I'll pull the shoulder bag around front, where it will stay. Heavier items (laptop, batteries) will go into the ruck, immediate access items such as commo gear (VHF set, satphone plus regular phones) and the like will stay in the shoulder bag. I've done this for weeks at a time in the Sudan. All fairly light and easy compared to the amount of crap I used to regularly haul around as an infantryman.
Anyway, somebody who complains about the weight of a MBP hurting his shoulders = weak. There's no getting around that.
