Apple tree stroke rehab

This is an easy therapy to do as I walk to and from the car. Our Haralson apple tree has a 1.5 inch thick branch at head height.  I grab it with both hands and just hang from the limb, works the finger flexors to just hold on. I last maybe  1 minute. Then I stand and just using my left arm push and pull myself away and toward the limb, initially I had to use both arms to do this. This came from Rowland Gale who had a website called hemiplegiarecovery and he called it pipe in a tree. This should only be done after you consult your therapist/doctor, you wouldn't want to fall and hurt yourself.
