Intermidiate Cardio

achnburn

Hi,

I am trying to find a cardio workout video to do. I have found beginner ones that are simply walk up and back, etc. and then there is insanity. I find insanity way too hard for me and have to take several breaks. It simply makes me feel discouraged doing any exercise at all. I play roller derby 3x a week, but seriously need to up my cardio endurance. I am struggling quitting smoking and am trying again tomorrow so I need something that isn't too rough on my lungs,but isn't extremely easy.. I don't have a gym membership and can't run (my hips hate me when I do). I don't have any cardio equipment in my house and its winter here so would rather not have to go outside.. I would prefer a workout video - probably between 20-30 minutes in length. Anyone know of any good ones or good youtube channels to turn to?
