Exercise is important for every person as it improves mood, fitness, and general health, not to mention weight. In my experience, medium to low impact exercise is best with Panhypopituitarism so to not make your fatigue and pain worse. In my opinion, yoga is a relaxing, low impact way to exercise even if SOD/ONH impacts your balance. Also, I think it is worth it to walk or run when/if you feel well enough and when the weather allows it.
