should you be training apps every single day if you want to have a visible six pack well in my opinion no first of all you need to be aware of the fact that if your body fat percentage is not low enough then you're not going to see them anyway no matter how hard you train them second point my recommendation would be to actually treat them as if they're any other muscle group so train them maybe once twice per week but for 10 15 maybe even 20 minutes pick three to four effective exercises and be consistent with doing them placing sufficient overload in order to promote muscle growth
