I need a better cardio workout?

You can either do any workout that anyone here will suggest or you can do what I do to lose weight when I have a fight coming up. Go to your local sports store and buy a $15 Sauna suit. You might not look cute at the gym but wear it and TRUST ME you will sweat your butt off and you will lose that weight quick. I lost 10lbs in 1 week. Its not healthy to lose too much weight at once but this will definitely work.
