Luka Modric's fitness secrets: How Croatia's captain defies age at 40

Portugal and Croatia are set to face off at Toronto Stadium tomorrow, with a spot in the last 16 of the FIFA World Cup 2026 on the line. The match features two European heavyweights led by veteran stars defying age: Cristiano Ronaldo and Luka Modric. Croatia's captain, at 40 years old, is poised to earn his 202nd cap after becoming the oldest player in World Cup history to provide an assist, at 40 years and 291 days, setting up Nikola Vlašić's winning goal against Ghana.

Physical attributes that defy age

Modric, weighing just under 10.5 stone (66 kg), combines balance, agility, coordination, and stamina. His low center of gravity helps him shield the ball, turn quickly, and change direction at speed. His light frame reduces strain on muscles and joints, while his strength allows him to retain possession in tight spaces. He has turned his seemingly frail physique into a powerful tool, always staying a step ahead.

The training regimen behind the longevity

Vlatko Vučetić, an associate professor at the University of Zagreb's Faculty of Kinesiology and Modric's personal trainer since 2012, shared the three goals they set: maintain fitness, prevent injuries, and extend his career. Modric initially aimed to play until 36 but now continues at 40 in a top European league and as national team captain.

Vučetić revealed that Modric completes a 45-minute workout before training, performed religiously on 350 days per year. The routine includes resistance band exercises, arm and shoulder strengthening, core work, and leg exercises. Vučetić emphasized the importance of such a regime after age 30, when muscle mass loss requires increased workload. When Modric was 39, his metabolic age was below 30, thanks to his commitment to injury prevention, rest, and variable training loads.

Cognitive edge and motor intelligence

Modric's longevity is not solely physical. Vučetić highlighted his cognitive attributes and motor intelligence—his ability to make quick decisions and read the game. Modric rarely wastes energy by arriving late; he scans his surroundings, adjusts his body position, and plans his next move before receiving the ball.
