Run...run....and run some more.
Run for 30 minutes, three time a week. Have adequate shoes designed for running. If you do a heavy leg workout in the middle of the week, then use the elliptical on that same day instead of running....example:
WED: Legs/Run or elliptical
SAT & SUN: Rest!
That is my typical workout plan when I began running and doing Cardio. That's how I did it. Be patient with it and your results will come. Make sure you eat extra lean protein on the days you run so that you deprive your muscles of amino acids and nutrients.
