How to get the exercise in

Well I lost another 1.8 pounds this week.  Now if I could figure out how to get some exercise in.  I have been doing  some walking at the local track but with the nice weather I should be outside.  If I get energetic in the morning maybe I will take a walk around the block.  Hopefully once I get outside and do some walking I will get into it and do more of it.  I really need to do some exercise to start to tone up this flabby body.
