He hadn't, but his appearance at the 2020 Charles Schwab Challenge was in fact the result of a huge bulking diet in the quest for distance.
DeChambeau's physique was all the more surprising for golf fans to digest because he had emerged looking like The Hulk after he was forced to quarantine during the COVID-19 pandemic.
It was quite a sight. And in absolute fairness to DeChambeau it worked. He led the PGA Tour in driving distance in 2020 and 2021, averaging 322.1 and 323.7 yards respectively.
But it came a huge cost. Now the captain of LIV Golf's Crushers GC side has admitted that he has made a mistake.
Appearing on the 5 Clubs podcast, DeChambeau said he wouldn't encourage others to follow his path.
He told the podcast:

DeChambeau was asked why he goes to such extremes in his approach to golf.
So would he recommend his approach?
It wasn't just DeChambeau's gut that "got messed up". He tore the labrum in his left hip as a consequence of his speed training. It was an injury that heavily impacted his 2022. He was advised by doctors not to play in The Masters but ignored their advice.
DeChambeau also fractured the hamate bone in his left wrist. He exacerbated that injury by slipping over playing ping pong before the PIF Saudi International in February.
That was before all hell broke loose in the world of professional golf and the 2020 U.S. Open champion joined LIV.
