Do not injure your back. You only have one. If you can store your
instrument at waist level it will make lifting and moving it easier.
Plant your legs close to the accordion and lift with both
hands. Have your knees behind or even with your toes, which means leaning your upper legs and butt back and bending forward some at the waist only. (And you won’t topple forward!) Keep your head up, eyes forward not down, and your back straight. Move your core to follow your arms; don’t just rotate your arms.
Setting it down uses the same rules. These are basic weightlifting rules and will serve you well.
I've taught piano accordion for many years. I've been playing nonstop since I was nine. As a veteran alternative school teacher and teacher of different learners, I teach all ages. I especially love to work with adults who are trying to remember how to be beginners. My lessons are seriously individualized. In my home in North Oakland.
