I have fibro and I find the more consistent I am with my training, the easier it is to manage my symptoms. I do have days that I just need to rest, but I don't let that go on for more than one day, then I force myself to get back to it. It's easy for me to sit on the couch, but I have learned to push through it. I'd rather slow down my workout than not workout at all. if I can't run or do an intense fitness class, I'll switch to the pool, which makes me feel great!
