I have gone to the first 2 sessions of my cardiac rehab. It feels good to walk on the treadmill and ride a stationary bike. They made the 2nd session a little harder than the first just to put my stress on my circulatory system. The therapist asked me how I felt after the work out. I said "I didn't have a heart attack and die". She agreed that was a good sign.
I can't wait to be able to run again.
My weight dropped dramatically from my initial weigh in- I think it is all water weight. Once that is all gone- it's really going to get hard to lose the pounds.
