I have yet to be banded but have been working with a trainer on my cardio. Sometimes, you dont need to increase the time you are doing the cardio just switch what you are doing. For example, I do cardio for 20 minutes in a pattern where I am going forward for 2 minutes with the resistance at 6 and the incline at 7 and then I go backwards for a minute with the resistance still at 6 but the incline at 4. According to my trainer my body is always switching up so it doesn't have time to get "used to" the routine. Hope that helps!
