Welcome to Gym Log's weekly fitness news roundup. Instead of sticking to one corner of the fitness world, this column follows the stories people are actually talking about across strength training, HYROX, CrossFit, bodybuilding, competition, exercise science and the wider fitness industry.
Here are some of the biggest developments from the week ending September 18, 2026.
HYROX Changes Rules After Viral Beijing Incident
HYROX changed its event procedures after Australian athlete Joanna Wietrzyk continued a Beijing race after experiencing bowel incontinence and went on to win. HYROX co-founder Moritz Fürste said the organization made a mistake by not reacting immediately and said rulebook changes and new procedures were put in place.
The story became one of the week's biggest viral fitness stories. On September 18, Wietrzyk apologized, said she regretted not stepping off the course and announced that she was withdrawing from the race and forfeiting the points she earned.
HYROX Keeps Expanding
The incident arrived during a period of rapid growth for HYROX. Reuters reported that the company's founders recently partnered with L Catterton and bought back a majority stake from Infront Sports & Media in a deal widely reported at around €600 million.
HYROX also has a busy calendar ahead, with events including Toronto in October and Vancouver in December.
Olympia Week Is Almost Here
The 2026 Olympia takes place in Las Vegas from September 24–27. The main weekend includes Men's Bodybuilding, 212, Classic Physique, Men's Physique, Women's Bodybuilding and other professional divisions.
The event is also broader than the main bodybuilding contests, with the Amateur Olympia, expo activities and other strength events taking place around Olympia week.
Rogue Invitational Returns to Scotland
The 2026 Rogue Invitational is scheduled for October 23–25 in Aberdeen, Scotland. Rogue says the event will once again bring elite CrossFit, Strongman and Strongwoman competition together under one roof.
It will also be the final year of the Rogue Invitational in Aberdeen, making this year's event a notable stop on the competition calendar.
Three Minutes of Sprinting, Hundreds of Molecular Changes
Newly publicized exercise research compared six 30-second all-out cycling sprints with 90 minutes of moderate cycling. The researchers found much larger immediate changes in measured blood proteins and metabolites after the sprint protocol.
The finding is interesting but should not be reduced to 'three minutes beats 90 minutes.' The participants were young healthy men, the full interval session took about 23 minutes, and the study measured biological responses rather than establishing a universal workout prescription.
A Weird One: Chocolate and Resistance Training
One of the more unusual recent exercise-science stories looked at whether smelling chocolate could influence resistance-training performance. The small study reported more repetitions in the chocolate-odor condition without a corresponding increase in perceived exertion.
It is an interesting research result, not a reason to replace a training program with chocolate. Small experimental findings need replication before they become practical recommendations.
What to Watch Next Week
The next seven days should be especially busy. The Olympia begins September 24, HYROX continues its international calendar, and the broader strength-sports schedule is building toward the Rogue Invitational in October.
As always, the useful part for everyday lifters is separating the spectacle from the training lesson. Watch the competitions, follow the research and then keep doing the work that fits your own goals.
The Gym Log Takeaway
Fitness is bigger than one training style. Strength, bodybuilding, CrossFit, HYROX, running, nutrition and exercise science all overlap in interesting ways.
