I am a fitness instructor but since I was in the hospital recently for neuro cardio syncapy I can hardly tolerate exercising. If I even work out for 5 minutes I can hardly walk afterwards. It's so odd that this is happening to me. The clients come in to workout and I can't even work out with them. Thank God for an understanding boss. At least for the moment. She's afraid I'm going to collapse again so she has encouraged me not to workout.
