So one needs to search for some exercise routine that you actually enjoy. It may be something as simple as walking the dog. And this benefits both you and the dog. There are so many ways to exercise that you need to keep searching for one that speaks to you and this may be several that you do in sequence. Keep searching. With only modest resources, but good health, life and even old age can be beautiful.
