Bravo @barbarn, Getting in the necessary exercise is not so difficult if it becomes part of the daily routine. I do about 10-12 minutes of core stabilization exercises and toe lifts faithfully every morning like brushing my teeth. I read my daily newspaper while peddling a stationary bicycle for a half hour in the garage. Its so much better than reading it on the sofa. I tend to spend a lot of time at my desk, especially with all of the Zoom meetings these days, so I take a few minutes of break standing up and sitting down 20 times from a chair. If weather permits, my wife and I will take a 20-30 minute walk after supper to help our digestion and we think we sleep better as a result. In bits and pieces, we get in the requisite exercise. My severe spinal stenosis and neuropathy are not getting better, but at age 88, I believe this approach is keeping it from getting worse as rapidly as it might if left to its own natural progression.

A dozen years ago, I saw a top neurosurgeon who looked at my lumbar spine MRI and was surprised that I could walk. A neurologist told me that half the men my age were in wheelchairs or needing canes. (Actually, half the men men my age are deceased.) Neither they, nor anyone else that I saw had any advice that was any better than to try to avoid surgery and to keep exercising.
