I've never had the PFT test, but all I want to know today is how good of a workout is this for a 73-year-old man? I am hoping for confirmation from a physician, such as you, that this is more of a workout, and a more strenuous workout, than most men my age do. What's your evaluation of the level, frequency, and intensity of my workout? By following this exercise regimen, I want to feel good about myself. Can you confirm that?
