Samantha Montgomery Testimonial for Vacupractor
So after trying to hold the suction as long as I could get it to stay I noticed that I was in fact able to make my legs go lower and lower each time so once i got them to the floor without immediately breaking the seal I stopped. Afterwards my back felt lovely. Kind of tingly in the absence of pain at least my lower back did. I even noticed i can actually almost lay down with my back flat on the floor after.
