It's all good Nate. I suggest that you mix and match the various cardio activities as well as cardio duration and intensities for best results.
Once a week, get a cardio activity in for a longer-duration and steady state pace, such as 30-45 minutes on the elliptical machine or running or brisk walking.
Once a week, get a shorter-duration and high intensity workout in, such as doing interval training of either fast-paced running distances for one minute with about the same amount of time recoverying with walking. Do this for about 20-30 minutes.
Once a week go all out, such as 500 meters on the rowing machine as fast as you can, or running a mile as fast as you can, or seeing how many strides you can complete on the elliptical trainer for 5 to 10 minutes. I like to set the elliptical trainer at a resistance of 10 and an incline of 10 (with 20 being max).
Just hit it 3 times a week and be steady.
