Re: Elderly Exercise?
Don't expect too much too soon from exercise.
Build up very carefully, despite what the seventy year old marathon runner from down the street demonstrates. [by making it look easy]
He has probably spent spent a lifetime to get where he is today.
The human body will adapt to do anything you want it too, provided you give it time to develop; the older you are, the longer it will take. BE PATIENT....
Choose something you like doing, consistency is the key to getting and keeping fit. Consider it a lifetime quest rather than a flash in the pan. Getting fit and loosing weight are not good reasons to exercise, you will not keep it up. They might give you the incentive to start an exercise program, but your love of the activity you choose will take over after the novelty has worn off.
Sounds like you expected to come back at the same level that you were at when you stopped running Mark. A mistake I have made many times after a lay off.
