LAS VEGAS — Hafthor Björnsson, the colossus human better known as Thor, stood barefoot over a barbell loaded with 1,135 pounds, a weight so absurd it seemed more fitting for a forklift.
He wrapped his baseball mitt-size hands around the bar. His face crunched into a grimace, and the bar bowed as he pulled. A crowd of biohackers, tech investors, wellness evangelists and influencers were captivated, eager to see whether a 6-foot-9, 400-plus-pound Icelandic strongman could give the Enhanced Games the exclamation point it had been selling.
