I'm just finishing up for the day. I did a lighter workout but still went full time. I'm so glad I didn't allow myself to get down yesterday for missing. And thanks Udog for the encouragement not to work out, it would have been too much for my body. I think I might be getting sick or fighting something :/ I felt sick to my stomach this morning.
I really think I want to start running but it always bothered my knees when I was younger. Of course, I didn't realize that anytime my knees get cold I get joint pain. (2 of my kids are the same way, scary enough)
I agree with Ergophobe on the running shoe suggestions and web site. The entire post was great. I had several of my Nutrition & Exercise college professors recommend that exact site, magazine, and strategy back when I was in school.
Also, since you had problems with your knees in the past, be very careful... PLEASE. Jogging is brutal on the knees, and I don't feel I'm going too far in suggesting you see a doctor before you hit hard jogging up.
However, since I know that's not realistic

D), here are some suggestions:
1) Good shoes can make a big difference, especially if you pronate or suppinate.
2)
For every pound you gain, you are putting about 4 pounds of extra stress on your knee. Ignoring that was part of what caused my knee injury.
3) Start off with intervals, as that will reduce the chance of injury. A simple example would be to walk for 4 minutes, jog for 1, walk for 4, jog another. Over time you can increase your jogging lengths.
I hope that helps.
As for your sickness, I hope you are feeling better soon.
like wolfy, i worked on upper body yesterday too. my lower body is pretty good but i also need to work on core which i did along side upper body yesterday.

I'm very happy to see you back - I was afraid we lost you!
I agree, aspartame makes me hungry as well.
My butt isn't hurting on the bike anymore. Did I get big callouses? Is my butt somehow impossibly flatter than it was before?
This is normal. Your weak flabby soft tissue became mighty soft tissue, and no longer fears the bike seat.
