I had a six pack at one point but that has gone away ahah, I still have the outlines when I lift my shirt up around the obliques area and then that pelvic V definition. It took me seriously around 2-4 months of intense cardio/ab workouts to get to the point I was at because of the fast weight loss I experienced, my body had excess skin so it took a decent time to get rid of but I took protein, ate lean meats, less carbs, more fruits and did around 30 minutes to 1 hour of cardio along with a ridiculous amount of ab workouts.
Right now I would say I got the top two abs below my pecs in terms of definition but the rest has gone away, have to get back into the groove of ab workouts.... hate them though haha
Pretty much, gotta follow the one's with the advice and knowledge :P
The one thing I don't understand is that when you do have a six pack or starting to get one, your girlfriend loves it but then tells you she loves you the way you look, so that when your six pack goes away, she starts oogling celebrities with six packs and then you tell her that you would get a six pack again but then she is like I love you to the way you are and you don't need one, but still oogles the celebrities.... it is just like do you want me to have a six pack or want me to have to cancel the cable and internet so you can't look at them and make me extremely confused.
I just don't understand, us men are willing to put in the effort to get a six pack but when you say you love us the way we are and then eye up other men with six packs, what is the point?! We are getting mind raped
