Right now I do about 15 minutes of cardio three times a week, do you think it would be better to keep fat off if I ran 30 minutes twice a week instead? I would run more but I am trying to bulk up a little, and my cardio is pretty solid I am just trying to keep it strong. If not though, what do you guys think would be a good cardio plan for keeping my heart strong but keeping fat gain down to a minimum while bulking.
