I did workout in the past but got a bit bored with it. Instead I now walk 6-10 kms every day and enjoy that. I give myself a day off on Sunday and in a week usually walk about 50 kms. Since becoming a widow I find that my walking time is very therapeutic as I do a lot of thinking and working things out in my head during my walks.
I never work out as such, I just go walking for 3k's around were I live, most days but not week-ends if my friend is also coming for a walk. I don't walk on my own anymore, as I've misplaced my iPod charger, as I'd always used that, while walking on my own.
