Anyone who struggles to maintain a steady exercise regiment gets it:
I keep weight down by one way and one way only: exercise. I could eat grass my whole life and I'd still gain weight. I have to exercise. Generally about an hour's worth, with at least half being jogging. As long as I do that, I'm OK.
For me, however, I'm also a creature of habit. When I worked at a massive mega-bank years ago, I was able to exercise in the mornings and then do stairs during my breaks at the company. That's because the building was over a quarter of a mile long, and had about a half dozen stairwells that were five stories high. Starting at one end and walking and running the stairs five days a week, along with my morning workouts, I was about where I needed to be. For a fifty year old, I was in fairly good shape.
Leaving there, it took a while to get back into a routine. And at this stage in life, going a week without exercise is like Tim Allen in The Santa Clause. But I finally found a good routine with a walk path through some nearby woods that, so far at least, are right by our house. A couple times thorough those in the morning and afternoon and it works about the same.
Since my wife's heart attack, however, we've not been able to get back into things. Starting with Covid, we began exercising together as we were both home. Which was nice. But since then she's been in therapy and that's left me high and dry. Call me a creature of habit, but having gotten used to having her with me made it tough to go back out on my own. Plus bad weather and then getting Covid didn't help.
Nonetheless, as Covid wanes and hopefully the weather turns a bit, we should be back soon. She's almost done with her therapy, and the goal is to have her back where we were when this all happened. It can't happen too soon. I feel the several months off of exercising. The only good news was the loss of appetite from Covid. Though, as I said, even grazing on grass has its limits for helping where weight is concerned.
