Some people are fanatics about exercise and fitness while others are the polar opposite. There are some who have no choice in the matter. Military personnel, unless they want to get kicked out of their respective services, are required to maintain some level of fitness at all times.
This major category includes the following subcategories. The idea that you need special equipment to exercise with and pay something to someone to maintain any level of fitness is a myth. It’s a myth perpetuated by those who stand to profit from it.
I suffered injuries just before and during my 20 years of military service. Still, I managed to retire with all of my limbs and internal organs intact. Some of those injuries have come back to haunt me, so that distance walking is about the only form of exercise I can tolerate these days. I don’t know if I can blame some of my current conditions on military training, and I’m not going to bother. I’m drawing a military pension and that’s enough.
At the age of 60, I find a lot of simple exercises not so simple anymore. Due to a previous shoulder condition, I can no longer do push-ups. Because of a lower left leg condition, I can’t jog for more than a few seconds at a time. Well, at least I can still walk a mile or more at a time.
