Can't say I agree with you there Cord... I mean, the problem with bulking isn't with the concept per se, it's with how people abuse it. I'm always seeing these fat guys cramming pop tarts and saying they're 'on a bulk' - it's possible to increase your calories without letting everything go to pot. The main problem with bulking cycles, is that people guys think "oh, I'll just eat everything in sight, do no cardio, and lift weights - the more weight I gain the better!" This is obviously wrong, but it doesn't mean that bulking doesn't work.
I'll just talk about what I'm doing right now as an example of bulking that works - I've put on 11 lbs, almost entirely muscle, in a month. I eat 5-6 times a day, relatively healthy meals, drink plenty of water, and use milk for some extra, easy to ingest, calories. I'm not eating a ridiculous amount, but enough that I stay anabolic throughout the day. I may not be *as* cut as I was a month ago, but frankly there's very little difference (I still have a six-pack), it still falls within the acceptable <12% bf criteria I set at the start - hell, I'm nearer 10% anyway! I think that my experience proves that it is possible to gain relatively large amounts of muscle fast, without any supplementation (I'm not taking anything), meaintain a healthy lifestyle, and not bloat like Ronnie Coleman in the off season
Of course, anecdotal evidence could make this the exception rather than the rule - I might just be lucky with the genetics (severe mesomorph as it is).
Anyway, looking too skinny... well, as COrd says, keep up your protein intake. If you can't get it through chicken/fish etc., then it's time to look at a protein shake, but don't bother unless you really can't get it any other way. The other thing that's worth looking at is how you distribute your calories throughout the day. Do you eat too little for breakfast, and too much for supper? Breakfast is an important meal, because you've just fasted for 7-10 hours (if you're getting enough sleep), so make sure you resupply your body.
Anyway, didn't mean to hijack the thread into a "bulking: does it work?" debate, but just thought I'd share a bit of personal experience
