Walking for Fitness

Walked for an hour and a half at the archery range today. I was huffing & puffing but my friend wasn't breathing hard at all. Just shows I need to do more cardio. She's been going to a gym and chasing her two little boys. But I feel that if I keep walking an hour a day I'll soon be able to keep up with her. We live far apart so we can't normally walk together. She used to belly dance to. I keep trying to talk her into taking it up again. We'll see.
