I feel SO GREAT! I was just able to walk 30 mins ( 1 mile ) on the treadclimber. I am sweaty and funky and so damn happy I could do it. The knee was ok, we'll see what happens. By the way, I had also downloaded a stand up show with Paula Poundstone onto my ipod. I laughed so hard. She has great timing and very funny without being vulgar. It was fun to laugh and walk at the same time. If your interested it's a Bravo network show, look it up on itunes. Off to clean the house.
