I appreciate his other advice though and yours and everyone else's. My stamina is still good but now starting my 50's I have to start to be more active and proactive.
entropy’s program is good. I would not disagree with any of it. But brisk/fast walking outside is nicer plus you can buy and use a weighted vest to add to the workout, if you want to call it one
He is also very smart to do his fast incline walk every day, no exceptions. This kind of consistency is very helpful to the mind too.
