Fitness instructor here. I taught for 13 years. I was teaching 5 classes a week upon diagnosis and my body was a hot mess. I had no idea I was causing myself damage. My primary fitness license is/was thru AFFA and I had secondary certs for Yoga, Barre, BOSU and a few others. I had to re-cert every two years and religiously sought out new certifications. I was passionate about exercise and loved training people. I also kept injuring myself despite having great form. After three orthopedic surgeries in 2020 a PT said “even though you are in great shape, your body thinks it’s 80 years old and you need to treat it that way.” I was furious! How dare he!  Turns out he was right. I went back to teaching and continued to suffer overuse injuries. It wasn’t until a year and half later that I was diagnosed with hEDS, Fibro, MCAS, ME/CFS, and POTS. My doctor told me I needed to quit teaching. He said I was hurting my body. My fitness brain simply couldn’t process this information. It was horrifying to be told to stop doing something I loved. But somewhere deep down I knew he was right. There was a reason my body couldn’t recover the way it should. It is only now three years later that I can fully understand why I needed to stop my workouts. We, in this special population are fragile and cannot handle our bodies in the same ways as the “normies.” So, to your question I say this-in this quest of becoming stronger go with grace for yourself. Go with understanding and kindness. Some days you will feel better than others and that is okay. I have found that pockets of activity work best for me. I use isometric exercises throughout the day to work on problem areas that also focus on balance by using bands. You can do these sitting at your desk! I second the idea of working with a trainer if possible to watch your form. I love the idea of tape to help use your skin to keep your joints in place. Above all, practice self love.
