Arnold and Cardio

Hi guys I was searching around and could not find any concrete evidence that arnold did any cardio or Maybe he ran a fatburner on cycle.What caused the dry hard look.Anyone with a answer you are welcome.

for what it's worth, in his 'Encyclopaedia of Bodybuilding', Arnold talks of running 'a fast mile and a half' after a workout..

So after every workout he would probably do some fartlek or something for 20-30 mins.I guess his recovery was pretty good since he did not have a 9-5 JOB except for bodybuilding plenty of rest for him.I think the compounds he used to the mg was alot for him to do such heavy workouts and cardio.Thanks Mack
