Thanks for the welcome. I am sure I found the right place to be, You are all so helpful. I was reading about the tredmill. I love using mine in the winter. Summer time I ride my bike. One day I will go between 6-7 miles and other days just around here for 30 min. but I make sure to do one every day. Thats a promise I made to doctor. A nice benefit I got from riding 6 miles is I met a lonely older lady sitting out in her yard just wanting someone to talk to. So now I have a new friend.
