Once you try this you will freak at how many other people are out in parking lots sitting in their cars. A lot of people use it as get away time from the office, school, whatever. If you just sit there and look natural people don’t even look over at you.
I haven’t figured out any hanging positions that work for me other than over the steering wheel. I tried straight down but the weight was laying on the floor board. A resistance band might work that you push with a foot or you could try running a strap around the brake peddle and pulling on it.
I in no way recommend this while driving. I do some manual stretching while driving sometimes but that is it.
I think the dull ache is a sign of fatigue. If I don’t have it I don’t think I have worked out enough.
