At our ages, especially us elders, we have been beat up so much over the years that I believe there is no one correct answer that fits all. Other than to pay attention to the kind of pain, euphoria, discomfort, etc and let that be the guide. By doing that a person will be able to select by trial and error just what exercises work and which do not. Just keep on keeping on with as balanced a program as you can.
I use a mix of bike riding, free weights, machines, swimming and just lying back and resting. My body tells me when I'm out of balance. True misery happens when I don't listen and it has to speak louder.
