Ok, I'm somewhat new to the whole cardio thing. I've always been about putting on size. It's the summer and I gotta put together a little experiment. I did a clean bulker my previous cycle doing cardio 30min ED. I will be doing 45min ED now and I'd like to know from you guys when you step on that machine what are the usual options you choose? Fat burn? Cardio? Fit Test? Steady HR? I was doing Cardio 45min trying to keep my HR at 135-151 but I felt that I lost way too much size. Let me know what you guys think so I can begin doing that.
