Anaerobic -vs- Aerobic Exercise

Just a week or so ago, I posted a picture showing a temperature of -31°F. Today, the temperature was +34°F. Yes, that is a PLUS sign. A 65°F swing in only a couple of days. If it wasn't for all the frost on the road, I would have pulled the bike out and called it riding weather. The air temperature may have changed pretty quickly but the road temperatures changes much more slowly so it was pretty slick.

I'm just about near the end of my free month at the Alaska Club and I have to admit, I really enjoyed the strength training. I also learned from the trainers on staff, that pushing myself hard when doing aerobic exercise was counter productive. Not necessarily dangerous just not getting the result I've been looking for. For the last couple of years, I would push my heart rate to 90-100% of maximum (for my age so it's not really that high) for long periods of time thinking that it would help get me into shape quicker. Doing this, I'm told, turned my aerobic exercice to anaerobic which apparantly consumes muscle mass instead of fat and much fewer calories. I've stopped pushing myself that hard for the last week but it is probably too soon to see any difference. A questionable side benefit is the workouts are easier but longer. Not what I was looking for. Once I get back from Barrow, I plan to sign up for a year at the Alaska Club to add regular strength training to my routine. Plus all of their treadmills have heart monitors that actualy work. Also, the environment is more conducive to exercise. I just need to try and figure out a way for it to fit into my schedule. I've actually had to drive to work three days per week for the last month instead of walking and riding the bus. To me, that seems a little counter productive.

  1. Hmmm...I did not know that if you pushed yourself so hard it was no longer an aerobic workout. Thanks for sharing!

    I wish we had an Alaska Club. I went with a friend once in Wasilla when I was visiting. It's such a nice atmosphere and there are friendly people there to help you out. That's one thing I'm looking forward to when we leave Nome and move somewhere 'big city' in AK. Hah!
