That seems like quite a bit of cardio. I can understand wanting to be at the gym all day every day, i was the same at your age. Just understand that you can burn yourself out quickly doing that.

I would suggest keeping your cardio at a very low intensity, because you dont want to over stimulate your CNS on your off lifting days. Pushing heavey wieghts with compound movements will punish your body enough without prolonged cardio. Pushing yourself like this will ultimately hinder your strength gains, so walk, dont run, if you must.
