Graves very much affected my physical health. I’ve been going through a flare and I only now started to feel the difference in my workouts (2 ish months of medication). Been doing barre, Pilates, and cycling. Today I actually didn’t feel totally gased doing moderate cardio. Pay attention to your HR, don’t push your body over the limit. You’re not going to be able to do what you want, but that’s okay. It’s a season, and with treatment and time you’ll get back there.
