you made some nice progress for sure. Sounds like there is a lot more room to grow too. Myself, I started when I was about 15 yrs old. I weighed less than you though, and I was 6 foot tall. I weighed about 140 lbs at 6 foot. I think Ive got the skinny guy gene. 3 yrs later when I graduated high school I was up to 185 lbs, so thats 45 lbs in 3 yrs. It comes on fast at first, rather easy. If you started at 165 lbs at just about 5 ft 6" then you werent too skinny to start out. Looking real solid. Keep on with Phil, he helped me achieve a better physique and I had been at it for well over 20 yrs.
