I ran for 30 years. I hated it.
But I sure liked the resulting physical fitness.
I haven’t been running for 18 months, due to injury and illness.
I hate the lack of aerobic fitness far more than I hated running.
Sorry for your current troubles!
I like to stay active - running in a straight line and back again, or even in a circle just doesn’t do it for me.
I have an indoor exercise bike (with all the fun programs on it) and we have an elliptical machine that’s easy on the knees, but I would SO much rather get my exercise mucking out the barn, walking with my dogs, gardening and snow shoeing or skiing in the winter months.
