have i got abs acceptable? because i'm not sure if i have to continue the exercise or not (sorry for the english but i'm italian)
Gaining muscle is not a "once and done" type thing. You must use it or lose it, as with knowledge.
Search for the term "reversibility principle".
Whats better than a six pack? A eight pack whats better than that? A better tined eight pack what s better than that? A even more well toned eight pack you can only make your abs stronger and stronger if I where you I would just keep working out ,your abs untill the day you die because getting in better shape will help your health
