I'm not getting thinner, I'm getting taller

Saw Merilyn today for the first time in several months and she commented that I was looking thinner. This made me laugh because I am still 16 pounds off my thinnest from last year. But she isn't the only one who has said this. As I looked in the mirror, I noticed that my posture is getting a bit better. I can only attribute that to my weighs/intervals training. I mean, all that planking has to be good for something, right? This was the incentive to keep up the interval training.
