Hi
i'm turning 18 in may so that's very soon
i've grown about an inch since last year
i didnt care about my height back then only since last summer
so is My goal REALISTIC? or i should expect less?
what do you guys think
my father is about an inch or two taller then me and my mom is short maybe 5'2
brother is 5'11 but he's in his late twenties now
i dont know if i'll reach his height or not,and wether i should blame my genes or my activity level,since we have alot of tall people in our family that are 6 feet plus i should have inherited that but my bad luck,it looks like i didnt!!

Nobody can tell you that , i can say yes only for motivational purpose.You must live and see will you grow or not.But you must try as hard as you can to make yourself grow.

I think you can, believe in yourself and work for it!

I think you can too. Major reason being that your brother has achieved that height
Stick to a healthy lifestyle and keep the stress away.

You should decrease your goal?
You should not make your goal become stressful.
I talk the realistic.
I see that you are almost 18 already, you are just almost finish growing.
of course you can't gain 3 inches, but you can gain to 1 or 2 inches.
Try swimming 2 times a week, swimming is a complete exercise.
1. Health ( Deep breathing)
2. Build muscle and lose fat (the movement of your body in resistance)
3. height
(you pull your body every doing breast stroke, water has lower gravity).
Don't take any hgh pills, don't stressed too much.
Do eat balanced diet.
Good luck.
Following this routine for 6 months, you grow 1 inches is not impossible.
Don't do too much, give time for your body to rest.

Shinbone routine.

This is not a plug or spam. I'm just providing useful information. I have nothing to do with that site, but it does have a lot of resources on increasing height during and after puberty.
