P90X / Rock Climb / Cardio

tuduis

So today is going to be my first day kicking off P90X. I've already completed around an hour of cardio, as this is my daily routine at lunch M-F and is one of the only few things that keeps me sane at work. Anyhow I have a few questions prior to me starting.

1. From those that have successfully complete P90X, do you think it'd still be okay for me to do 30-45 minutes of light/medium cardio during lunch followed by P90X about 5-6 hours later?

2. For The Rockclimbers - Which routine, Classic or Lean, would you recommend I follow to improve in climbing? I'm sure I can't go wrong with either but I was just wondering if anyone had any opinions.

Thanks!
