My doctor told me that adding an exercise regimen that kept my heart rate accelerated 30-40 minutes almost every day would be good for me. Doing that (and changing eating habits) helped me lose weight. My question is: is 60 minutes of cardio-exercise “twice as good” as 30 minutes? Is 45 minutes 50% better for me than 30? Or is there a diminishing return on incremental increases like that?

For a long time, I have had lumps on the bottom of one foot in the arch area, toward the inner half of my foot. They are the size of marbles. I don’t think they are getting larger. But now I get pain in that area when walking or if I stand for a long time. What’s going on? Are these tumors that need to be cut out?
