Strongman has stripped ‘trans woman’ Jammie Booker of her World’s Strongest Woman title.
Booker’s Instagram bio notes that she is a personal trainer and professional strongwoman. She has never spoken publicly about whether she is a cisgender or transgender woman.
Booker was crowned the winner of the Official Strongman Games World Championships 2025 in Arlington, Texas, on Sunday (23 November).
Her victory saw her surpass former world champion Andrea Thompson of Great Britain, who, in a clip taken while she was standing on the podium, can be seen looking frustrated and saying “this is bull***t. Can we go??” before storming off of the stage.
However, on Tuesday (27 November), organisers of the event, Strongman Corporation, took to Facebook to announce that Booker had been stripped of her title after “being informed” that “an athlete who is biologically male and who now identifies as female competed in the Women’s Open category”.
The statement noted that Booker was disqualified because she violated the event’s trans-exclusionary policy which states that “competitors can only compete in the category for the biological sex recorded at birth”.
“All athlete points and places will be altered accordingly to ensure that the rightful places are allocated to each of the Women’s Open athletes,” the post added, meaning Thompson now holds the World’s Strongest Woman title.
Thompson posted about her delayed win on social media, writing that it was “overshadowed by scandal and dishonesty”.
The organisers emphasised that the competition remains an inclusive one: “Official Strongman is inclusive and proud to run events which do not discriminate against athletes based on personal characteristics. Any athlete is welcome. But it is our responsibility to ensure fairness and ensure athletes are assigned to men or women’s categories based on whether they are recorded as male or female at birth.”
Many reports, including one commissioned by the Canadian Centre for Ethics in Sport, have found that trans women do not have any advantages over any other women, when competing in elite sport, if existing rules are followed.
A 2024 study, published in the British Journal of Sports Medicine, revealed that the absolute hand grip strength of the 23 participating trans athletes (after at least one year of hormone therapy) was lower than that of the 19 participating cis men but higher than that of the 21 participating cis women. Hand grip strength is considered an indicator of overall muscle strength.
Joanna Harper, a medical physicist at Loughborough University in the UK, explained that “after going through hormone therapy, trans women are now moving their bodies with reduced aerobic capacity, reduced muscle mass.” This reduced muscle mass can lead to disadvantages in terms of speed, recovery and endurance.
