i was 22% bf at the end of my bulk, now im like 9% or 10% , if i were so strict whit the cardio and diet that would take me like 3-4 weeks, for you can take you like 4-6 weeks
but do your cardio , 40 mins everyday its enough and low the carbs to only before and after training,and in the other foods just eat protein/fibrous carbs, eat like 8 times a day, remove the sodium and consome shits, thats all , no shortcuts its like that..
