We all Spend too much time sitting -- or standing, but not freely moving -- and certainly not getting our heart and respiratory rate up, or raising a sweat. Our modern work-style makes getting sufficient Exercise difficult, so I long ago made it a habit to get in some aerobic activity outside my working hours.
I used to get up early and go for a 3-mile run in the pre-dawn hours before I had breakfast and the phone started ringing. Later in the day, about every second day, I would lift weights. Sometimes I didn't feel like doing it, but I did it anyway to stay in the routine and not lose the progress I'd made.
I think I picked up this habit of making time for exercise in reaction to my father discouraging sports and exercise in general. He had some good ideas, but he was clearly nobody to listen to for health advice. He smoked 2 packs a day since the age of 15 and couldn't walk a half block without being in extreme pain.
My father died of a heart attack when I was 15, which left me free to quit high school band and substitute working at a gym after school to earn educational credits. This enabled me to build some muscle, which helps burn more calories and keep off the fat.
This has paid off by helping prevent diabetes throughout life. It makes a lot of sense to spend the same time many people spend parked in front of a TV, watching "the Beautiful People", to spend that time working on my own health.
Keep in mind that no amount of exercise can keep up with the rate bad food choices can pack on the pounds. It's important to eat a mostly plant-based diet and avoid refined carbs, sweets, alcohol, and processed foods (loaded with chemicals).
Exercise moderately 3-4 times a week, plus losing some excess fat alone is usually enough to reverse the progress to full diabetes. This is a proven fact!
Opportunities to get some exercise are all around us: park further from where you're going and walk the rest of the way; take the stairs, not the elevator; take a quick walk at lunch. It can be done -- and you'll feel better for doing it!
