Likewise. I have been powerlifting for over 7 years now and there are things about my body I would have never realised until they had gotten much worse. Like that I always leaned slightly to the left because of how I had my mouse, and I had a way overdeveloped right spinal erector and funky core because of it. Likewise still not perfect, but simply leagues ahead of my former physical self.
I wouldn't recommend powerlifting to everyone, but some kind of weight training and especially the squat and deadlift. You can pick a weight training style to suit your goals though. I have moved to a more powerlifting / bodybuilding regiment as I have reached the strength level I am happy with at my current bodyweight.
