Well you could always have your bodyfat measured and compare it to your bodyfat when you hit your target weight. Some gyms have a set of calipers and shouldn't charge you much, if anything to measure it.

Congrats on getting closer to your goal though sir. Here's a nice ab exercise for you to try when you get a chance. (at the end of the video)
