It’s not about avoiding a clumsy look, it’s about being effective and efficient in what you are doing. I don’t have anything about getting out of a car, but I do have one for getting out of a modern chair, which I think is similar. https://freeyourneck.com/blog/alexander-technique-tip-93-how-to-get-out-of-a-modern-chair/

I will try to sure remember this

Hi Joanne,

Regarding your first question, people often ask which muscles to use for a particular task. For sitting in a chair (or really any movement) it’s not about using your back or your legs because everyone always uses the whole body the whole time. You are already using your back and your legs (and the rest of your body) to sit in or rise from a chair. The point of the Alexander Technique is to learn to use your body in a way that is coordinated and organized, and not haphazard.

For your second question, the general strength of the body usually reflects how it is used. The person who climbs stairs generally becomes stronger at climbing stairs. As you attempt to sit in a chair without falling into the chair, you will probably become stronger in that way.
