Q: I have recently found out I have the lung capacity of a 132-year-old man and am in the process of purchasing a rowing machine, the good kind. My question is basically, am I purchasing the right equipment? I have a good treadmill that I use and which does a good job on the legs but I want something for the lungs.

A: Virtually any type of cardio exercise will benefit your lungs. Both the rowing machine and treadmill would be beneficial. Alternate between the two of them.
