Exercise and being overwhelmed by it

My exercise this morning consisted of a 45 minute slow walk.  How many times do I have to remind myself that a pedometer is necessary?  Anyways, I have just finished performing exercises to strengthen my neck.  I have been having issues with my neck which lasted but all of 10-15 minutes.  I have no issue with planning but I do have an issue with how I view exercise.  Instead of exercise being something I do either because it is fun and it is beneficial, I view it as a chore.  Wow.  I have just realize that even the concept of exercise overwhelms me.  I would like to start changing that mindset and just "move a muscle", but how do I overcome being so overwhelmed by exercise as well as diet?
