You can't beat walking and swimming for getting in shape and staying fit. I am 83 years old and swim one kilometer a day five to six days a week. It takes me about 44 minutes from start to finish. Also, I advise many folks my age, who complain that they cannot breath properly while swimming, to learn to use a swim mask and snorkel----both of which are very simple to learn to use.

. I always have one day a week when I do no exercise, or very little, I was told that our muscles need some recovery time.
