At the start of this season, I was 5'10. Now, in April, I am almost 6'1, and I didn't start growing until January.. My minimum body weight went from 188 to 204. Since getting back to lifting about a month ago, my chest, hamstrings and glutes have almost doubled in size. I can't even fit in my 18.5" neck shirts anymore....I have been eating excess of 5,000 calories a day most of the time. I was supposed to be done growing, but in the last three months have grown more vertically then I have in the last three years...how common is growth like this?
