Why doesn't aerobic exercise seem to "transfer"?
For aerobics, I like cycling and swimming. I am strong in both and can keep a good pace for a long time. The other day it was raining and the pool was closed so I decided to run on a treadmill and was dying after 10 minutes. This surprised me since I'm in good aerobic shape (or so I thought). It wasn't my leg muscles getting tired--it was just feeling hard to breathe. Why doesn't good aerobic conditioning in one activity transfer to another one?
