SIr Isaac Newton and Exercise

What does Isaac Newton have to do with exercise?  It's those damnable laws of motion.  Specifically, the one about "objects at rest tend to remain at rest unless acted on by an outside force."

I'd really slacked off on my running over the last couple of months.  What with one thing--okay, one excuse after another--the days turned into weeks without running consistently, if at all.  So when I decided it was past time to get serious about it again, it was distinctly unpleasant.  Gasping like a fish out of water and sweating like a pig and I still couldn't do my previous regular route.  Just.  Couldn't.  Do.  It.

So I accepted the unpleasant fact that I had squandered my hard won fitness and had to drop back and punt.  I went back to the program I started with over a year ago: Couch Potato to 5K.  I didn't go all the way back to the very beginning, just to the start of the fifth week, a little over halfway through.  And now, two weeks later, I'm very close to getting back to running the 5K again.

What does this have to do with Isaac Newton?  It's the fact that  aerobic exercise is never not work.  Pretty much by definition, really; if you aren't working hard, it isn't aerobic.  But, like pushing a piece of heavy furniture across the floor, it's less work if you don't let up once you finally get it moving.  I know that.  I knew that.  But I guess I needed a reminder.  My running regimen is easier and more enjoyable when I do it consistently.

In other news:  WORLDCON is only two weeks away!  If any of you are going to be there, or live in the area, let me know!  It's always nice to put a face to the name of an imaginary friend*.

*"Imaginary Friend" is a term of art my lovely and talented wife [livejournal.com profile] snippy uses to describe people she only knows via online communication.

ANerobic is when you're working really hard. Aerobic can be when you're doing nothing at all. I'm very aerobic right now with my butt in my chair. When you run hard and start to feel a burn/tightness in your legs, THAT'S ANerobic. You're no longer distributing enough oxygen and you're going into a different metabolic cycle.
