8lbs over what time period? A 1/2 pound a week is about as fast as you can do it healthy. Some will say up to a pound a week... but I think that is a little bit aggressive.
Coach Jenny wrote: Sara, that is wonderful news and you are on target not only for healthy weight loss but a new active lifestyle with your fiance. Think of where you began when 15-20 minutes was tough! Walk around with an 8-pound weight at the gym and you will soon see what a difference every pound makes. Your body is transforming and your life is taking on the attributes of an active person. All of which are signs of success.
To answer your question, about a pound per week is healthy. Some lose less and some a little more. The more gradually you lose weight, the better chance it is in the form of fat rather than water and muscle. As you get more fit and continue to lose weight I will continue to tweak your training program and make it a little more challenging.
By the way, have you and your fiance and Trish set a 5K race date yet?

8 pounds, that's awesome! I'm not an expert, but it sees like that is a healthy weight loss progression. And if you keep this momentum up, you'll be right on track to reaching your goal!
