Hi Deborah! I can't answer your question, but it is so cool to see someone from Jerusalem here! Happy new years and I hope you'll find out what causes your problems after you do aerobics!

My goal is to start out walking one time around my work place every work day (about a half of mile), and to increase that each week until I'm up to about half hour a day of walking.

Also I plan to hike each Saturday, starting out at half and hour and then progressing to whatever feels right.

I recently got my National Geographic Topographical maps to go with my Pocket PC and GPS receiver, so I'm all ready to go!! Plus, it's lots of FUN to hike in Arizona and the weather is getting much better (cooler).

Thanks for this fitness challenge. This is pretty neat!
