I have weight related plantar fasciitis, achilles tendonitis, and a mild case of arthritis in my lower back and hips. Some of that is from carrying Paul Bunyon for 9 months, but a lot of it is from being overweight. I don't say this for pity...just to let you know where I am coming from.
My family activities, vacation plans, and day to day productivity are greatly affected by the fact that my mobility is an issue. My ability to walk for exercise or heaven forbid, run is severely limited. Is it possible? Sure. I could physically make my body do it for a short amount of time, but going into it I know that I will pay for it for days after - hindering further progress, at least temporarily.
This is one reason why I want to pursue weight loss surgery. I want this to be a non-issue ASAP. Let me get on with my stinking life already!
Still working on it - Keep praying!
