I had to retire almost 3 years ago due to health reasons,bad back,knees,nsulin pump and etc.ostlywhat I have done is sit in front of my computer since there isn't a lot of physical activity I can do.About 3 months ago I joined the local You-Fit gym and I work out fairley hard and I'm seeing positive results already like lower blood sugars and return of muscle mass.I'm not looking to bulk up,merely strength and some definition.I know there are a ot of guys in my age range who have grown soft and flabby but I intend to go down fighting.
