Cardio: Exercise or Heart Rate?

[deltreefitness]

Just got back from the gym - I HATE tredmills... So I hardly ever uttilize them while doing cardio. Anyways, my question is;

Does it matter if you use the tredmill or the Precore eliptical machine to do cardio? Running on a tredmill is just too hard on my knees it seems. Does it really matter what I choose to burn off that extra fat with? Or is it truly about reaching certain heart rates? TIA

I dont think it really matters bro....Both work the hearth and you can use both to burn fat....One is easier on your knees and the other isn't...You do the math

Besides i don't see any reason in doing anything you don't like....If you love what you do, you'll do it alot longer...
Just my opinion...
