I've had 5 PT Appointments,and the last 2 were more vigorous.My MPT,Master Physical Therapist doesn't want me doing my Walking-Work outs at Home,or even marching in line.He prefers the Exercises we do + Walking 1/2 Mile at the Track,then sitting/resting my Spine between each lap.I have this silly belief that I'm not putting in 1/2 Mile unless I Walk the 1/2 without stopping.My MPT and another MPT told me I am still getting in the 1/2 Mile.We're working on strenthening my Spine,so perhaps I can eventually build up to a more strenous Work-Out.I'm doing the Exercises at Home,but feel I'm not getting enough Exercise.I want so bad to do 3-5 Day's of hard Work-out,but guess I have to face the fact that it has to be slow go,because my Spine is so degenerated and deteriorated.
