In 2019, Bryson DeChambeau made a public declaration that seemed almost delusional: he was going to outmuscle the golf course. He was going to eat, train, and supplement his way to a body that could drive the ball so far that traditional course management would become irrelevant. The golf establishment politely dismissed the idea. By the end of the 2020 US Open, played at Winged Foot, a course specifically designed to punish long, wayward driving, DeChambeau had won by six shots. The fitness revolution in golf had its origin story.
The Numbers That Shocked the Tour
DeChambeau's transformation was quantifiable in a way that made it impossible to dismiss as anomalous. His average driving distance increased from 297.7 yards in 2018 to 344.4 yards in 2020 — a gain of nearly 47 yards on a tour where the average player improves by fractions of a yard per season. His clubhead speed went from 116 mph to over 130 mph. He had essentially engineered himself into a different category of player, one for whom par fives had ceased to exist in any meaningful tactical sense.
The Copycat Effect
The response across the tour was initially sceptical, then curious, then urgent. Within two years of DeChambeau's 2020 US Open win, the average driving distance on the PGA Tour had increased by over 4 yards — the largest single-year jump in the statistic's recorded history. Training methodology that had previously been dismissed as bodybuilding-adjacent entered mainstream golf fitness coaching. Speed training, overspeed protocols, rotational strength work, and specific nutrition programmes became standard practice at the highest levels of the game.
Jon Rahm's Evolution
Rahm's physical development since 2021 represents the most complete version of the new golf fitness model. Unlike DeChambeau, who pursued mass and raw power, Rahm has focused on rotational power combined with mobility — an approach that has given him additional distance without compromising the ball-striking precision that defines his game. His average driving distance is now 311 yards, up from 295 five years ago, but his greens-in-regulation percentage has actually improved over the same period.
“Five years ago, distance was something that happened to you. Now it's something you train for. That shift is permanent.”
— Phil Kenyon, golf performance coach, European Tour conference, 2025
What the USGA and R&A Are Doing About It
The governing bodies have responded to the distance explosion with a combination of equipment restriction and course lengthening. The Model Local Rule on ball distance, allowing professional events to mandate a shorter-flying ball, came into effect for all major championships in 2026. The reaction from players has ranged from resigned acceptance to genuine enthusiasm — several top-ranked players have argued that the rollback restores strategic interest to courses that distance had rendered obsolete.
The 2026 Fitness Landscape: Where We Are Now
- ·Average tour driving distance: 302.4 yards (up from 285 in 2015)
- ·Players averaging over 320 yards: 27 (up from 3 in 2015)
- ·Tour fitness trainer employment: up 340% since 2019
- ·Average tour player body fat percentage: 10.2% (down from 14.8% in 2015)
- ·Speed training programs now used by: over 90% of top-50 players
The Recreational Impact
The fitness revolution has filtered down to club golfers. Instruction programmes specifically targeting speed and rotational power for recreational players have grown 180% since 2021. The message: you don't need to be a professional athlete to add meaningful distance through targeted training.
