I don't like to exercise either. I have a pretty sedentary lifestyle though, and if I don't exercise, I feel it. So, DH and I work out together. We go to our Y (about 15-20 min away), and work out 3x's/week. I'm trying to add something on the off days. But, I'm busy, just not physically like you are. You can count your work with your animals as exercise. Just increasing your activity level, I think, is important. It really helps with seasonal issues (if you live up north--like I do).
