I finally received a diagnosis 2 months ago, and now that I'm on Coumadin, I feel so much better! For the past 2 years, though, I have done next to nothing physically. I am able to walk and cook and take care of myself now, but I am weak and need to get my strength and endurance back. I'm ready to start going to a gym and exercising (in a pool, first, to build strength). Are there any restrictions, worries, etc. that I need to watch for when doing this? How have you all gotten back in shape after being diagnosed (assuming you had a period of chronic illness)?
