Even as he was in the thick of the fight during the 2017 U.S. Open at Erin Hills, Brooks Koepka found time to get into the gym for a big lift.

Before his final round on Sunday, which ended with the first major PGA championship in his career, Koepka was working out with trainer Joey Diovisalvi (who also works with Dustin Johnson, arguably the fittest man in golf), getting in a bench press.

That work in the gym really paid off: Koepka tied the record for the lowest U.S. Open score at 16-under for his win, matching fellow star Rory McIlroy’s 2011 performance.

While some golfers like to keep everything focused on the course during a tournament—especially a major—Koepka has no problem getting in a morning lift, even when he’s one of the top guys on the leaderboard. Like fellow golf stars such as Johnson, McIlroy, and Rickie Fowler, Koepka trains hard and all but destroys the notion that golfers can’t train like other athletes.

Here’s a look at Koepka’s best workout moments in the gym.
