Getting six pack abs is a waste of time IMO. I know lots of ladyboys out there that have six packs, and they think they're the shit. Then, they see you with 17" biceps (not huge, but decent size) and challenge you to an arm wrestle. You slaughter them, then make up some BS and challenge your other arm. You annihilate them again, without abandon. They leave, six pack intact (but pride sorely lacking).
I'm going to break some news to you: the male body isn't supposed to be at 7-9% body fat when it's reached it's mature state. Sorry gentlemen, but it's not. Your body wants to be around 10-13%, which is cut enough to have definition, but not cut enough to have shredded abs. Getting lower requires a deep understanding of your body, careful dietary planning, often supplements (ECA stacks, steroids, etc.), and a bit of luck with genetics. You see lots of "skinny fat" people (thin people with a bit of a belly), but how often do you see a dude that's genuinely skinny? Rarely, and the ones that are have the genetics for it.
People need to stop fucking worrying about six packs. Go to the gym, follow a basic 5 x 5 routine if you've never lifted seriously before, and
get strong. You know what's fucking impressive? Benching 225lbs+ for reps (I don't mean this one time max shit, I mean for reps. Bench it three sets of 8 reps, 5 sets of 5 reps, whatever.) Squatting 400lbs+ for reps. Deading 450lbs+ for reps. I've never met a single guy who could dead over 350 who didn't have the muscle development to back it up.
Sure, it's not a "glamorous" workout like P90X, but P90X is bullshit anyway. P90X is good for people who don't do any other activity of any kind and who don't do any strength building. A friend of mine swears by P90X, and in a year I got leaner, bigger, and stronger than he did. Of course I did, I did weight training with a focus on building strength, not size. He did P90X. He's still a ladyboy. I had to go buy new shirts because my shoulders, chest, and triceps/biceps had gotten too big for the ones I had.
The best part about not having abs is not having abs. They are a bitch to maintain. Years ago, when I was 18, I used to have a six pack. I used to be that lean, ripped guy that had little muscle development anywhere else. I used to do fucking situps before I went to bed. I did situps when I woke up. I did situps in the middle of class. I did situps when I was fucking. Hell, back then I'd do situps when I was typing shit like this. Then, as my metabolism reached maturity, the six pack disappeared. No amount of situps brought them back, either, and I realized that I had to keep my BF% low enough to make them visible.
Fuck. That. I'd rather be "bigger", with a defined outline than a ripped six pack, since it means I actually get to eat real food. You want a six pack? I'll tell you how:
+ Put your body into ketosis. Cut out carbs (shoot for under 75g/day of carbs-- good luck), eat high fat/high protein meals. Aim for .75g/protein per pound that you weigh.
+ Do HIIT. High-intensity interval training is the best thing for cutting fat. It also sucks donkey balls to actually do. If you don't know what it is, Google it.
+ Add weight to your ab routine.
BAM- you'll have a six pack... as soon as you get rid of all the fat. Meanwhile, in the three months you're doing that, I'll bulk up a little. I'll put on some more weight, some of which will be fat, but I'll also be able to LIFT more weight. Then, come spring, I'll cut down for a few weeks so I'm sitting around 10-11%BF. You'll have your six pack, but I'll still look more impressive on the beach.
Why? Shoulders + chest + arms + legs = win. Keep chasing your six pack, folks. I don't need mine
