On the other thread where you posted pics I was actually going to say that. Your mid section went down quiet a bit and your arms were much thicker. Honestly I think it's muscle memory. When I took about 4 years off working out and started back up in about 3 months my body responded tremendously and everyone swore I was on stuff even though I was natural. Keep the consistency. It won't last long though. Your body will plateau and you will have to work harder and harder to put on the inches.
