I have a desk job and got in terrible physical condition called deconditioned. Within one use I noticed leg ankle knee pain subsiding. now after 3wks of use I am off pain meds and can sjop fot groceries now. it has given me my life back. prior to using it I felt like my body was dragging my legs around. now I feel a smoothotion when just walking in daily routine and no pain. range of motion on legs greatly proved.
