Inertia. Back in school I learned that inertia is the tendency of a body at rest to stay at rest and the tendency of a body in motion to stay in motion. Inertia explains why you are pushed back into your seat when the car or bus moves suddenly forward—and why the car won’t stop immediately when you hit the brakes. It’s a good principle to know.
Inertia applies in other ways, too. Like to my exercise program. During the Christmas holidays I didn’t get out running much. After the holidays ended, I caught a nasty bug that was going around and didn’t have the energy to exercise for two weeks. And then work got really busy, and I was spending too many hours on my rear in front of the computer. When a day finally came that I was able to get out and run, I really didn’t want to. I knew I needed to, but I did not want to. Inertia wanted to keep this body at rest.
Once I pushed myself—with help from hubby—to get out and move, it wasn’t so bad. I did two miles and felt good about it.
… At this point, I intended to turn inspirational and tell you all how I kept at my running program, and it just got better and better. Inertia keeping my body in motion and all that. Unfortunately, that did not happen. Work and bad weather kept me inside for a while longer. The next time I got out to run, I tried to do my usual three miles. It was a disaster. My legs tired quickly, and I think the pace of my walk breaks was faster than that of my running. The next day my legs ached, and my right knee kept giving out. I skipped a couple more days of running, and my next outing was not fun at all. Apparently inertia is not so easily overcome.
It takes a force to overcome inertia; the greater the mass, the greater the force required. Can that be why it’s easier to get our dog to move than me? Hmmm. Might be some other principles involved there, too. Still, it can be done. We ran on the Springwater Trail yesterday—just 2.5 miles, so as not to overdo it. Trees were beginning to leaf out, flower buds were swelling, signs of spring everywhere. Beauty can be a force, too, at least for me. It makes the effort to keep those legs moving worthwhile.
How about you? Where in your life is inertia keeping you from moving? And what force will it take to break inertia’s hold?
Boy, that really hit home for me, Susan. I have found it way to easy following surgery to allow inertia to keep me planted in my chair rather than getting up and strengthening the muscles around my new joint. I did it today, though. And it was nice to get out. Now, if I can just keep it up!
The first time is the hardest…followed by the second… but it does get easier. Keep up the good work, Fred!
I always find that the most difficult bit of exercise is the next one.
Actually, I think the most difficult exercise is the one I’m in the middle of. The next one I can always postpone…
I think keeping the ertia pumping is crucial. Sometimes I feel like just settling into a blob. I can’t even be bothered to get up off the couch and go to bed. At those times I discover I have high blood pressure, high blood sugar and other things were it is not so helpful to be top of the class. Fortunately our city council has built marvellous new parklands across the road. A good place to walk, but not always. On the weekend I took the dog there and hoped to make several loops of the maze of paths. But I ended up surrounded by half a dozen small children all trying to pat Cato, so I couldn’t really walk very fast. Luckily their mothers all came and too them away, otherwise I might be standing over there still.
Cato must be a cute dog to attract so much attention. But it’s nice you have a good place to walk–at least on days when it isn’t crowded with kids. And yes, there are definite drawbacks to becoming a blob, as enticing as it may sometimes be!
