Trudging Through Mud - Resistance Cardio

It was one of those cardio workouts where you feel like you are trudging through mud.  I did resistance cardio today at Pura Vida Club.  I pumped up the resistance and worried more about time than mileage.  So I did 20 minutes on the Precor then 25 minutes on the elliptical machine.  Ended up getting in 4.5 miles with moderately high resistance.  Then some ab work including planks and the plank side bends.  Cardio with resistance really makes you sweat!  Great workout and I was out of the gym within an hour.
