Thanks JA, and Glen
Glenn, i appreciate your concern and also value your suggestions, however, i will not be doing any rehab in the environment you suggested.
Today i did my breathing exercises 6 times, body exercises and proper movement techniques three times, working with my chest mussels etc, and walked twice at 500 meters each time.
I felt good, and knew if it was going to be to much i would have to cut it back.
Tomorrow I will repeat that process until i can get just that bit further each day.
I am a very determined person, just ask the wife.
However i do know when to stop.
Thank you indeed for your suggestions Glen.
Leon
