I reccomend drawing a line on your wall with a pencil and than measure it with a straight edge like a notebook. I'm not doubting that you grew, but you never know that you might have grown more than an inch because half an inch ain't much. Be sure to work your back muscles so there's some sort of balance between those and your abbs.
DON'T WASTE YOUR MONEY ON INTERNET HEIGHT SCAMS - 99% OF THEM DON'T WORK - - YOGA STYLE STRETCHING, KICKING, HANGING & EXERCISES ARE THE ONLY WAY TO INCREASE YOUR HEIGHT IF YOU ARE AN ADULT (OR RISKY, EXPENSIVE SURGERY!) WE'VE RESEARCHED EVERYTHING AND CAN TELL YOU WHAT'S A SCAM AND WHAT IS WORTH CONSIDERING. IF THESE SO CALLED "MIRACLE" PRODUCTS ADVERTISED BY THESE INTERNET COMPANIES WORKED, THEY WOULD BE ON BILLBOARDS, TELEVISION AND THE RADIO AND WOULD BE KNOWN WORLDWIDE!!!!!
