Is this good enough?

I am 28 yrs. old , 5'4 and 188 pounds. I just bought a treadmill and for the last week I have been working out on it since last Monday 2-13-06 and have only missed 2 days. I get up in the morning before work and do between 45 to 50 minutes on it at a 3.3 pace. Does that sound like I am doing what I am suppose to be? Thanks for your help. Dorie Berry

When you are getting your cardio in with walking at a fast pace you are supposed to try and sing the Star Spangled Banner if you can sing it without being out of breath you are not going fast enough. Give it a try. If you are out walking with a friend you are not supposed to be able to carry on a conversation. If you can carry on a conversation you are not going fast enough. I have read this over and over again in walking articles and books.
