I am sitting here and imagining you doing the jumping jacks while holding your breasts so that they do not bounce, @Chrissy Cross .......way too funny ! ! Anyway, no I do not do the cardio workout part. I just got the app to check my heart rate. I do not want it to go up high in any case. the doctor said I should keep it below 60 if I can, because when it speeds up is when it will go into a-fib. So, I am still swimming and doing water exercises and walking with Bobby; but nothing that will push my heart rate up.
