A plus-size personal trainer from Wolverhampton has become an unexpected voice in the fitness world, challenging stereotypes about who can guide others toward better health. Her rise followed a viral YouTube video by influencer Joe Fazer.
Viral experiment draws attention
The 17-minute video, which questions whether a fat physical therapist (PT) can train effectively, has attracted 964,000 views and over 5,800 comments on Fazer’s channel with two million subscribers. In the video
- Rhiannon Cooper, 33, a neurodivergent trainer specializing in anxious and gym-averse clients, trains Fazer alongside a more conventional, six-pack-clad colleague.
- The video ends with a candid discussion among the trio, sparking widespread debate about body diversity in the fitness industry.
- Rhiannon addresses the core question directly: “Can a Fat PT effectively train me?”
Reflecting on the experience, Rhiannon recalled backlash. “I was told I was morally incorrect,” she says, referring to the traditional trainer’s reaction. Yet she remains steadfast in her mission to serve clients intimidated by the gym’s typical image, filling a vital gap for those with mental health challenges who might otherwise avoid exercise.
Spotlight on inclusive fitness
Rhiannon, founder of Not So Typical Fitness, now hosts the Not So Typical Fitness Podcast, guiding autistic, ADHD-diagnosed, and anxious individuals through fitness journeys. Her services include in-person sessions in Wolverhampton and online coaching for those underserved by mainstream gyms.
She explains the need for her approach: “There is no debate as to whether gym anxiety exists – it does. It’s more prevalent among people who are neurodivergent or plus-size. I’m here to help ease this anxiety so more people can get moving and improve their health and fitness. Stats tell us 74% of gym beginners wish there were more supportive environments and 80% who experience anxiety report that social support decreases their fear. This is why I do what I do – to make a difference to these people.”
Supporting research
- A 2021 Samsung study found 83% of Britons view the gym as intimidating. Half fear judgment, and 35% feel unfit to start.
- Anxiety UK notes that neurodivergent individuals, such as those with autism or ADHD, face higher risks of anxiety, often worsened in sensory-overloaded environments like gyms.
Rhiannon’s own late diagnosis of autism and ADHD at age 33 informs her work. Her latest programme, The 8-Week Gym Confidence System For Anxious Minds, draws on input from occupational therapists, neurodivergent trainers, and client self-testing to help users adapt gyms to their needs and build confidence without shame.
Challenging industry norms
Rhiannon asserts her unique perspective: “My value as a trainer isn’t diminished by my body size; it’s enhanced by my ability to connect with and support clients who need someone who truly understands their struggles.”
As a fat acceptance advocate, she has shared her message globally, including at the United Nations Commission on the Status of Women. Currently training for a strongwoman competition, she demonstrates that athleticism transcends body type. “It’s okay to be different, it’s okay to be fat. I can be fat and a good personal trainer,” she says.
The online response has been overwhelmingly positive. Thousands of comments praise her bravery and relatability, with viewers sharing that her approach could motivate them to return to exercise.
Personal philosophy and mission
Rhiannon frames success in personal training not by appearance but by empathy, knowledge, and client results: “Success as a personal trainer should be measured by knowledge, client results, and the ability to motivate and support people on their fitness journeys, not by appearance. It’s about empathy, understanding, and creating safe spaces for people who have historically been underserved by the fitness industry.”
Her journey to advocacy was long and varied, spanning 17 jobs in 12 industries, including saddle fitting, insurance sales, and call centre work. Personal experiences with neurodivergence, self-harm, and eating disorders have shaped her empathy and dedication to inclusive fitness.
Now 33, married to her wife, and openly pansexual, she channels her lived experiences into building a movement that prioritises all bodies and brains. Her mission also extends to neurodivergent youth, creating pathways to inclusion and confidence through fitness.
