Science Meets Strength: Department of Physiology to Support Rayno Nel’s world-beating strongman success

South African strongman Rayno Nel has made history by winning the 2025 World’s Strongest Man (WSM) competition, and remarkably, he did so in his very first appearance. His groundbreaking victory marks a milestone for the continent, as he becomes the first South African, first African, and first athlete from the Southern Hemisphere to claim the coveted title.

Competing against some of the sport’s most experienced and decorated figures, Nel impressed spectators and judges alike with his consistency, composure, and remarkable strength, edging out former champions in one of the closest finishes in WSM history.

Scientific Support Behind the Strength

Following his world title win, Nel partnered with leading South African institutions, including the Department of Physiology and the Sports, Exercise and Medicine Lifestyle Institute (SEMLI) at the University of Pretoria, to establish a science-based foundation for his ongoing performance journey. Together with Limitless Longevity, Neurolink, and Precision Performance, the collaboration aims to assess and enhance Nel’s physical, neurological, and cognitive performance.

These advanced evaluations will help develop a personalised, evidence-based support system to optimise recovery, sustain peak performance, and build long-term resilience for future international competitions.

A Multidisciplinary Team Effort

The partnership brings together a team of experts across multiple fields:

• SEMLI & Department of Physiology (University of Pretoria): Prof Peet du Toit, Dr FC du Toit, Ms M Groenewald, Mr M Kleynhans
• Limitless Longevity: Mr Karel de Haas
• Neurolink: Dr Andre Vermeulen, Mr Tiaan Vermeulen
• Precision Performance: Mr Naat Loubser

Looking Ahead

For Rayno Nel, this victory marks only the beginning. With world-class scientific guidance now integrated into his training and recovery, he is poised not only to defend his title but also to inspire a new generation of African athletes to pursue excellence through the synergy of strength and science.
