I have Fibro and am also bone on bone in both knees, one worse than the other. Conventional exercise is not an option for me atm. I'm awaiting surgery for the sleeve and then a knee replacement. For now, since October, I joined my local gym which has a pool. I attended multiple group classes with various instructors. Most times don't mesh well with my schedule so I've taken the things that work for me and make my own routine. My husband has noticed, as have my clothes (lol) a definite loss of inches. And on the machine at the gym I've gained muscle mass and lost fat, even though the number on the scale has seemingly stayed the same. My husband also says I move better although I do still favor that one knee. If you've got a gym close by that has a pool, it would be worth the effort. I go 3 to 4 times a week, for at least an hour. I jog in place for 30 to 40 minutes, then finish with my strength exercises. Then, I treat myself to the hot tub. I can say that outside of pilates on a reformer, this is something I really look forward to since I've never been a huge exercise advocate. I love stretching and yoga, but I do that on my bed. Hope this helps. I know moving and staying active is key to keeping that Fibro pain at bay and in check. Sent from my SM-G998U using BariatricPal mobile app
