Every year, International Women’s Day celebrates the achievements of women across every industry.
In the world of health and fitness, that celebration feels especially meaningful.
Today, women are leading the way as personal trainers, athletes, fitness entrepreneurs, gym owners and educators. Strength training, endurance sport and competitive athletics are now spaces where women thrive.
But the modern fitness industry didn’t always look this way.
For much of history, women were discouraged from lifting weights, competing in sport, or training intensely. Exercise for women was often limited to light activity, based on outdated beliefs about health and femininity.
The women who challenged those ideas didn’t just change sport — they helped shape the fitness industry we know today.
This International Women’s Day, we’re celebrating the female fitness pioneers, athletes and entrepreneurs who helped transform the industry — and the women continuing to shape its future.
Early Female Fitness Pioneers
Katie Sandwina: One of the First Female Strength Athletes
Long before strength training became popular for women, Katie Sandwina was already demonstrating incredible feats of strength.
Born in Austria in the late 1800s, Sandwina performed as a circus strongwoman and gained global recognition for her lifting ability.
She famously defeated the renowned strongman Eugen Sandow in a weightlifting challenge, lifting more weight than him in front of a shocked audience.
Sandwina regularly lifted barbells weighing over 100kg and even performed lifts while holding her husband above her head.
At a time when women were discouraged from physical exertion, she proved something revolutionary:
Women could be strong.
Her legacy helped challenge early stereotypes surrounding women and strength training.
Bonnie Prudden: One of the First Female Fitness Advocates
In the mid-20th century, Bonnie Prudden became one of the first women to promote strength training for everyday health.
She hosted one of the earliest televised fitness programmes and advocated for better physical education in schools.
Her message was simple but powerful: exercise should be accessible to everyone, not just elite athletes.
Many of the principles she championed — strength training, functional movement and lifelong fitness — are now core components of modern personal training.
Influential British Women in Sport and Fitness
The UK has produced many influential female athletes who helped redefine what women can achieve in sport.
Dame Kelly Holmes: Inspiring a Generation of Female Athletes
Kelly Holmes made British sporting history at the 2004 Summer Olympics in Athens when she won gold medals in both the 800m and 1500m events.
Her double Olympic victory was a remarkable achievement and one of the most memorable moments in British athletics. It demonstrated not only incredible physical performance but also the determination and resilience required to succeed at the highest level of sport.
Holmes’ success inspired a generation of women and girls across the UK to pursue athletics, running and competitive sport.
Following her retirement from elite competition, she founded the Dame Kelly Holmes Trust, a charity that supports young people through sport, mentoring and personal development.
Her legacy continues to encourage participation in physical activity while highlighting the powerful role sport can play in building confidence and resilience.
Paula Radcliffe: One of the Greatest Marathon Runners in History
Paula Radcliffe is widely regarded as one of the greatest female marathon runners in history.
In 2003, she set a women’s marathon world record that stood for an incredible 16 years, highlighting the extraordinary level of endurance and mental toughness required in long-distance running.
Throughout her career, Radcliffe won multiple major marathons and became a dominant figure in international distance running.
Her achievements helped inspire a huge rise in running participation, particularly among women, with events such as the London Marathon seeing record numbers of female participants in the years that followed.
Radcliffe’s legacy continues to influence the running community today, encouraging more women to challenge themselves through endurance sport and long-distance events.
Women Who Pioneered Strength Sports
Judy Oakes: A Trailblazer for Women in Strength
Judy Oakes was one of Britain’s early pioneers of female strength in sport.
Competing in both athletics and powerlifting, she represented Great Britain in shot put while also setting multiple British powerlifting records during the 1970s and 1980s.
At a time when strength sports were still heavily male-dominated, Oakes helped challenge outdated stereotypes around women and weight training.
Her achievements demonstrated that women could excel in power-based sports, paving the way for the growing popularity of strength training, powerlifting and Olympic weightlifting among women today.
Athletes like Judy Oakes played an important role in shifting perceptions of female strength, helping open the door for future generations of women to pursue strength-focused sport and fitness.
Modern Icons of Female Athleticism
Jessica Ennis-Hill: Olympic Champion and Role Model
Jessica Ennis-Hill became one of Britain’s most celebrated athletes when she won gold in the heptathlon at the 2012 Summer Olympics in London.
The heptathlon is one of the most demanding events in athletics, combining seven disciplines including sprinting, jumping and throwing. It requires an exceptional balance of speed, strength, endurance and technical skill.
Ennis-Hill’s victory became one of the defining moments of the London Games and inspired thousands of women and girls across the UK to take up sport and athletics.
Beyond her Olympic success, she has continued to promote the importance of staying active, supporting initiatives that encourage participation in sport and fitness at all levels.
Her achievements helped demonstrate the incredible versatility and capability of female athletes, and she remains a powerful role model within British sport.
Tia-Clair Toomey: Dominating Functional Fitness
Tia-Clair Toomey is widely regarded as one of the most dominant athletes in functional fitness.
A multiple-time champion of the CrossFit Games, she has consistently demonstrated extraordinary levels of strength, endurance and athletic ability. Her training combines Olympic weightlifting, gymnastics, endurance and high-intensity conditioning, showcasing the incredible versatility required in modern fitness competitions.
In addition to her CrossFit success, Toomey has also competed internationally in Olympic weightlifting, representing Australia at the 2016 Summer Olympics in Rio de Janeiro.
Her achievements have helped redefine perceptions of female athletic performance, proving that strength, power and endurance can coexist at the highest level.
Today, she continues to inspire athletes and fitness enthusiasts around the world, encouraging more women to pursue strength training and competitive fitness.
Women Leading the Modern Fitness Industry
Athletes inspire the world, but many women are also shaping the fitness industry through entrepreneurship, coaching and education.
Krissy Cela: Fitness Entrepreneur and Community Builder
Krissy Cela has become one of the most influential entrepreneurs in the modern fitness industry.
As the founder of Oner Active and the training platform EvolveYou, she has built a global fitness community centred around strength training, confidence and empowerment.
Through social media, training programmes and education, Cela has inspired millions of women to feel stronger both physically and mentally.
But her impact goes beyond business.
Krissy also founded The Power Project, an initiative designed to introduce young girls to strength training and physical activity. The project focuses on building confidence, promoting healthy habits and helping young women develop a positive relationship with fitness from an early age.
By creating accessible opportunities for girls to experience sport and strength training, The Power Project reflects a wider mission within the fitness industry: making exercise inclusive, empowering and available to everyone.
Through entrepreneurship, education and community building, Krissy Cela represents a new generation of female leaders shaping the future of fitness.
Chloe Madeley: Promoting Evidence-Based Strength Training
Chloe Madeley represents a growing shift within the fitness industry towards evidence-based coaching and sustainable training.
As a qualified personal trainer, fitness author and strength coach, Madeley has built a strong platform encouraging women to focus on performance, strength and long-term health rather than quick fixes or unrealistic body standards.
Through her coaching, online programmes and educational content, she promotes resistance training as a powerful tool for improving confidence, building muscle and supporting overall wellbeing.
Madeley is also a strong advocate for helping women feel comfortable and confident in strength training environments, encouraging more women to move beyond traditional cardio-based exercise and embrace lifting weights.
Her approach reflects a wider evolution in the fitness industry — one that prioritises education, realistic expectations and empowering people to build sustainable fitness habits.
Laura Collett: Strength and Athleticism in Elite Sport
Elite sport showcases strength in many forms, and Laura Collett is a great example of the physical and mental resilience required to compete at the highest level.
Representing Team GB, Collett became an Olympic champion in team eventing at the 2020 Summer Olympics in Tokyo. Eventing combines dressage, cross-country and show jumping, making it one of the most demanding equestrian disciplines.
Success in the sport requires not only technical skill but also high levels of fitness, balance and coordination.
Collett’s career is also a story of perseverance. After suffering a serious fall in 2013 that left her with life-threatening injuries, she fought her way back to elite competition and eventually Olympic success.
Her journey highlights the determination, resilience and dedication that underpin elite performance in sport.
The Evolution of Women in Fitness
Over the past century, the role of women in sport and fitness has transformed dramatically.
What once began with a handful of pioneering athletes challenging social norms has evolved into a global movement of female athletes, coaches, and entrepreneurs shaping the future of health and performance.
Today, strength training is widely recognised as one of the most beneficial forms of exercise for women. Research consistently shows that resistance training can improve bone density, increase muscle mass, enhance metabolic health, and support long-term wellbeing.
Yet for decades, myths around women and strength persisted — including the idea that lifting weights would make women “bulky” or that intense training wasn’t suitable for female bodies.
Thanks to the athletes, coaches and educators who challenged these misconceptions, the narrative around women and fitness has completely changed.
Now, women around the world are embracing strength training, endurance sport, functional fitness, and competitive athletics in record numbers.
Why Representation in Fitness Matters
Seeing women succeed in fitness and sport plays a powerful role in encouraging participation.
When athletes like Jessica Ennis-Hill or Kelly Holmes succeed on the world stage, they inspire the next generation to believe that sport and physical achievement are possible for them too.
Likewise, entrepreneurs such as Krissy Cela demonstrate that women can lead successful fitness brands and global communities.
Representation helps break down barriers.
It shows women that fitness is not just about aesthetics or weight loss — it can be about strength, performance, confidence and empowerment.
And that shift in mindset is one of the most positive changes the fitness industry has seen.
The Rise of Female Personal Trainers
Another major shift in the fitness industry has been the growing number of women entering careers in personal training.
Female trainers are helping reshape how coaching is delivered by focusing on:
• Evidence-based training
• Building confidence through strength
• Creating inclusive gym environments
• Supporting long-term health and wellbeing
• Educating clients on sustainable habits
This approach reflects the broader evolution of the fitness industry — moving away from quick fixes and toward education, lifestyle change and long-term health.
For many people, working with a personal trainer is the first step toward building confidence in the gym and developing a healthier relationship with exercise.
The Next Generation of Women in Fitness
While it’s important to celebrate the pioneers of the past, the future of the fitness industry will be shaped by the next generation.
Across the UK and around the world, more women are entering careers in fitness than ever before.
They are becoming:
• Personal trainers
• Strength and conditioning coaches
• Sports scientists
• Gym owners
• Online fitness coaches
• Wellness educators
Each new coach, athlete or entrepreneur contributes to a growing movement that is making fitness more accessible and inclusive for everyone.
And as the industry continues to grow, female leaders will play an even bigger role in shaping how we approach health, exercise and wellbeing.
Celebrating Women in Fitness This International Women’s Day
From early strength pioneers like Katie Sandwina to modern fitness entrepreneurs like Krissy Cela, the story of women in fitness is one of resilience, determination and progress.
Each generation has pushed boundaries, challenged stereotypes and created new opportunities for the next.
Today, women are stronger, more visible and more influential in the fitness industry than ever before.
But the story isn’t finished.
Every woman stepping into a gym for the first time.
