I once wrote an article talking about the possibility of using reflexology to increase height. When the Yoko Height Increase insoles were reviewed, the theory behind how the yoko insoles work was from a blend of acupressure theory, reflexology, and magnetic field force. I personally have never done martial arts so I don’t know if the ancient theory if chi is true so acupressure is still untested. As for reflexology, I do know there are many foot massage places in my city and the subject they call their art is reflexology.
As for using magnets or magnetic theory to increase height and grow taller, I currently have not discovered any techniques or methods that claim to help people grow from the application of magnet theory or electromagnetism.
So, Nothing at this time. May be edited and added upon in the future.
