If you train at high intensity, yes your aerobic system will be taxed, however the nature of high intensity is that you will tire quickly and you will not be able to sustain long duration.
The way to train the aerobic system is to go for a minimum of 45 minutes. Keep it low intensity. Keep it easy. It won't feel like you're working hard, but you will reap the benefit.
As someone that practices HIIT I have a question. I don't do this currently on a regular basis simply because of the ice and ridiculously cold temperatures, but I try after dinner or sometimes before it go for a walk on my road. Understand at least a half-of-a-mile one way is a hill that from eye view doesn't seem like much but trust me it taxes you. So from a simple walk that I average 30-plus minutes do you think that falls under aerobic?
