IMO, exercise does not need to be strenuous. Better if it is not. Stretching is a big deal, which Zeke mentioned. Just range-of-motion stuff. Simply moving is helpful. Walking. I have always been intrigued by Tai Chi, but just have never adopted the practice. I really should just do that. Yoga is good. It incorporates physical, mental and spiritual. But I am not as drawn to Yoga as to Tai Chi. Tai Chi looks so fluid and calming. Yoga looks more intense. I don't need to be any more intense than I am.
