Running on a treadmill feels like a much harder workout, but I'm wondering if that's just because it puts more strain on my joints rather than making me work harder.

I like ellipticals just because I can have resistance in addition to incline.
I also feel like treadmill is the harder workout. Somebody smarter than us lay down some facts.

Then change the speed/resistance until it's harder. Cardio is for CARDIOvascular training, so just measure your heart rate and keep it in the right range
