Replying to Naturally growing

okay well basically im 16 years old. My dad is 5'4 and mom 5'2. I have been 5'5 for almost 2 years now and i think im done growing. I remember a long time ago, i was on some website that had ways to grow naturally but doing different stretches and such. It was mainly to grow out you upper body, since it said growing your legs is harder or something.

Anyways, i can find this site anymore and I want to know if anyone knows about sites like these and if the work outs actually work. Im Japanese and even my country's average height is taller then mine (5'7").
Thanks!
