In like 10th grade I was hitting 225 at like 130, 135 lbs. BUT (AND that’s capital fucking but with bottle rockets and lasers and other pyrotechnics effects) I had been coached/training by some very winning wrestling coaches for years at that point, and had weights at home, and 3 older brothers and many cousins to try to keep up with.
It was probably 20 years later before I hit 320lbs. at 160 though.
Interestingly enough, both times someone else was managing or directing my lifting.
