I never once visited a gym, but I have a couple of dumb bells and a pull-up bar. Push-ups, pull-ups, sit-ups, planks, and a few shoulder exercises with the dumb bells. Twice a week.
This is the result, about 6 weeks away from my 50th birthday. This is me. I'm never going to give in to old age. Age eventually wins, but I want to live the way I want to live. When my time comes, I won't be sorry.
Somewhere there is a saying, something like "It's not the number of years to your life, but the amount of life in your years." I'm sure I butchered that, but you get the picture.
Onward and upward.
