Hey, Dana. We have SO many articles about exercise, and I'll share a link to the archives so you can see if anything in there sparks a new idea for you. But first, since it sounds like you have a lot of neck issues (correct me if I'm wrong!), I've always loved this article and video from an occupational therapist who demonstrates a series of stretches that are good for the neck. Of course, it's not a workout, but you might find that they feel good and don't trigger an attack.

Keep in mind that walking and other forms of cardio are great workouts by themselves -- even in short intervals of 10 minutes. What about slow, careful weight training? Have you ever tried that or is it too intense?
I give you a lot of credit for continuing to pursue fitness with migraine. Motivation can be tough, even without it! Keep exploring. -Melissa, migraine team
