Just as an example, I started lifting at 15 or so. I used a basic 4x10 on bench, and as I recall I went from roughly 4x10x135 to 4x10x165 in a few months time. (with no idea about diet)

After that I was introduced to the SF 5x5 and within the next six months I broke 205 (a huge milestone for a 16yo) and didnt stop progressing untill freshman yr in college when I Hit 315. But of course i had learned a few things about diet by then.
