I'm sorry, but caliper readings are pretty inaccurate. Losing 20 pounds in 6 months is solid and believable, but it's hard to believe that you put on 20 lbs of muscle in 6 months. Generally accepted advice is that you can gain about 0.5 lb muscle/week, so I could see you putting on 12-15 lbs tops.

It's also very difficult to lose fat and gain muscle at the same time, especially if you're not a teenager anymore. Still, congrats on your progress!

Individual caliper readings have a pretty high margin of error- I've noticed up to 3% swings from week to week. But when the readings are done regularly and applied as a trend, it's pretty clear.

I've also changed my diet significantly- I eat way more protein and fat and almost no carbohydrates. I think that has as much to do with my fat loss as the exercise.

generally accepted advice isn't always right: I put on 17lbs of muscle in three months (Parris Island, SC). I was underweight at the time, and a teenager.

I did mention in my post that it doesn't apply to teenagers, although I should've been more explicit at that. Growing children can generally make tremendous progress, as can untrained novices.

Your post doesn't really refute my point anyways, because it's very hard to gain muscle and lose fat at the same time for adults. You're talking about one direction i.e. gaining muscle.
