Hey, I've started my 5 week long cut session and I've pretty much got my diet plan down but now I was just thinking about what Dr. X had said in another post. Something to the effect of not being in the fat burning zone until 20 mins of cardio has been done. I've only been doing 30 mins of cardio everyday. Do you think that maybe I should increase that to 40 mins or so to gain more fat burn? Or am I missing something?
