Do you like to run?

I don't mind running if it's the best exercise I can do to improve my cardio.
user
If you want to improve your cardio, you probably should run for a long time and with a lot of intensity.  You could also do cardio exercises like cycling or playing tennis.  A good mix of running, cycling, and tennis is probably the best.
