what is your weight, height and body fat % now?
Doing ab exercises will not give you a six pack (you already have one) - you need a body fat lower than 10% usually to see abs so you are wasting your time doing lots of reps for abs
it seems to me from what i understand you are trying to gain muscle and burn fat at the same time but whether or not you do that and are able to lose fat and build msucle fast at the same time depends on how fat you are, how out of shape you are (you seem to be in decent shape) and how long you havent been training because ONLY if you fall in those 3 categories = you'll be able to BOTH lose fat & build muscle fast at the same time
i now all that i am not a begginer,i have like about 15 or 16% bodyfat and i now that sit ups or any other abs exercicices will not give me a six pack,i am just asking what is your opinion about my abs workout
i do cardio,bpdybuiling and abs but i howredy have some god results in the chest,biceps,legs and shoulders
time of training:8 to 9 month
