I'm 17 at 6'0 and 150 lbs. But my father when he was 18 he was about 6'1 and 200 lbs but he was not fat and did not lift weights. Most of my fathers male cousins are 6'5 and his female cousins are 5'10 to 6'0. My ? is do you think i still may grow or have a growth spurt? I have never had a growth spurt i just slowly grow. In the last 3 years i really started working out and eating right. I still get acne and shave once a week does this mean i still have more to grow, my body shows no gains in strength so i hope i am not done growing.
