You are definitely lean enough but maybe you have put on more muscle than you would like. My trainer, Valerie Waters, believes that women can bulk up more than they might like. She trains Jennifer Garner and a bunch of other action-ladies. She subscribes to a different sort of workout where we actually use lighter weights than I ever used and it has helped me un-bulk somewhat. She has a great little device called the Valslide that helps you get lean and strong without bulking up.
I had discovered Val after reading about how she is Jennifer Garner's trainer. If you are looking for that type of lean, strong look I'd check out valslide.com. Great workouts. And it's not just about the looks. I just listened to an interview with a stunt woman who has worked with some of Val's girls and she said Val's gals do almost all of their own stunts because they are so fit and strong.
