If you're injuring yourself by walking around with a few extra kilos then you are so, so hilariously out of shape that any advice you can give is competely disregardable.

I avoided injury when backpacking through the Himalayas by tying helium balloons to by backpack for neutral buoyancy. Had to make slight adjustments as altitude changed, but it all worked out. I had my porter carry the helium tanks.

The OP said their legs were shaking just standing due to lack of exercise. So, they were literally that hilariously out of shape.
