You have no idea what Walker is taking
It's safe to say it's a LOT. He has gotten bigger and bigger, year after year, even after the kid was stupid huge.
To what else might you attribute his steady AND rapid growth? A near-magical training routine? Eating more rinsed beef?
I'm being sarcastic ☺️. A good diet and many years of hard training are certainly important, but be realistic here, Brian. Nick is Dallas McCarver all over again. The lad is 5'7" and pushing 300 in his off-season.
The human body isn't designed for such extremes. Put your head in the sand if you want, mate, but deep down, I think you know better.
