He's 16, not like 13 or 14, so to me not that impressive. I was much stronger then him already by 16 as I discovered weights by age 14. He's got great structure and form for sure and a good frame to build on, but not much mass at all. Just a wirery muscularly defined kid. My friends and I were much more built and strong than him by his age growing up. Still much more impressive than most Xbox, Facebook, instgram Justin bieber wannabe's these days.
