Now I read somewhere on this board that I should take my clen about 30 minutes before I do my cardio. My question is regarding my heart rate. I really dont want my heartrate above 139bps because then I will be burning muscle. I want to stay in my fat burning zone. The problem is that I find my heart rate at like 135ish as soon as I am on the cardio machine for 2 minutes. I have to go real slow to keep my HR down...is this normal or should I wait longer before I do my cardio?? Does it even matter as long as my HR is in the 130s for 30-45 minutes??
Sorry for all the questions but I am very curious, thanks.
