My younger sister, about a month ago, got our 83 yr old mother an exercycle which she is trying to use but when she peddles for more than 10 minutes gets chest pains. The Dr prescribed her nitro and told her not to bicycle for more than 10 minutes at a time. She is overweight, has congestive heart failure, only 1 kidney and bad knees and has never exercised. My sister is pushing her to exercise so they can fly to visit her 80 yr old sister for her B'day in August. She will have a wheelchair waiting at the airport and while visiting but my sister feels she needs to get into better shape for the trip.
I feel she should not be doing this exercycle thing at all...am I wrong?
