I've gained almost 30 pounds in the last 4 months, and I've seen (and felt) gains in my legs, arms and abdomen. The chest just won't do it though. So since I was told to eat more in general, it makes my midsection pop out, so to make it smaller, I do more ab exercises, which makes them even more disproportionally bigger compared to my chest. And thus the vicious cycle continues.
Eat small meals, often.
Nice advice Chuckie. But now for someone who can explain why. A small "meal" means about 15-25 g protein (for most people, if you're 6'3++ lemme know) and 50-100g carbohydrate, depending on activity level. More protein will not do anything except add unnecessary work for your liver and kidney to process and rid the body of the ammonia formed.
So the real advice here is this: unless you are doing steroids, those 30 lbs in the past 4 months are not all muscle at all. Whoever the bro-science nutritionist that told you to just eat more to gain weight didn't bother asking you if you wanted to gain lean mass or just mass. If you're storing bulk in your muscle, it's not solid muscle, but marbled muscle (fatty muscle), much like what makes steak juicy and tasty, but horrible for your arteries.
The most amount of muscle you probably naturally could synthesize, assuming adequate rest, sleep, not overeating (like it sounds like you have been), and perfect training is about 8 lbs of lean mass (be it actual contractile proteins or glycogen stored in the muscle) within your time period of 4 months, and really, this would only occur if you are past the initial starting period of learning how to lift weights correctly and are actually making slow and steady gains for the first time in your life.
So, working your abs will not make the abs stick out or shrink. It will make them fitter and able to do more reps, but they will not grow like your arms or legs unless you do a machine that adds resistance. Just like running won't grow your legs, doing tons of situps won't make them stick out anymore. You can make them stronger with resistance (those ab machines that add weight), but that's probably not your goal.
You store fat in front of your abs, and it's the first place fat is stored on men (other than our butt and hips). Because you've been doing the popular "bulking" routine, which is a poor choice indeed albeit everyone is an expert and it is not your fault you listened to people who don't know what they're talking about, you have to remove the layer of fat you put on there, and the bloat is from your overeating distending your abdomen.
Any sort of food will create an osmolality in your intestine that will draw water from the body into the intestine to normalize the osmolality. If you overeat, you're going to draw water into the small intestine, puff out your abs, and store more fat because you don't need that much blood sugar at once, and not ALL of the glucose will go to your burning muscles, if they even are sufficiently burning. Most will go to your adipose tissues, making you fat. Thank god you have adipose tissues to take up excess glucose because once they get inflamed, you get diabetes (sugar has no where to go but make your arteries sticky like maple syrup).
So my advice is to stop overeating and start eating a little bit less in terms of portion sizes. You do not want to feel stuffed. Maybe after another few months you will have reversed some of the the fat you stored in front of your sexy abs.
