I understand that "Abs are 70% diet and 30% training" and all of the other cliches out there about "how to get a six pack". This is not the purpose of this question.
I think all of those cliche sayings have ruined my focus on abs. I went from training hard 5 days a week to decently easy ab workouts 3 days a week because people kept on saying "abs are made in the kitchen". I do not want to know how to cut fat off of my abs because I don't have much as it is. I can see my abs and obliques very well and I am now working for ab depth and mass. 

So my question is, **how can I increase the depth of my abdominal cuts and the size of my abs**? I'm assuming that both are related in that - increasing ab size increases the depth of the cut. 

**Current Ab Workout Routine**

---

Currently, I am training abs 3 days a week for about 15 minutes. I usually pick three exercises and do as many sets of 20 reps as I can in 15 minutes. I can usually complete 3 - 4 sets which (or 180 - 240 reps). I switch it up every day and make sure I target obliques, lower and upper abs. I usually take one day to focus on hanging ab workouts so I'm not always on the floor.

*Current Exercise Regiment*

**Advice I was given**

I started thinking about this because of some advice I was given recently. Yesterday I auditioned to be a model in a new fitness magazine. The interviewer said that he would like to see me increase ab depth. He said that increasing reps (to 500/day) and training abs daily would be really increase the depth of my abs to make them really "pop". Does this sound like good advice?
