Work abs on cardio days or upper body?

[MGibbs65]

I love your workouts! Right now I'm doing Intensity Pyramid upper and lower body, with 50 mins of Turbo cardio between those days. My questions is should I work my abs on cardio days, or upper body days? And also, how many days a week is it safe to work your abs?
