Health doesn't operate in separate boxes
Meet Trilogy Health founder Fallon Parker
Nutrition, exercise and recovery do not happen independently, but the tools we use to manage them often do. Trilogy Health founder Fallon Parker is bringing the three together while asking a harder question: is giving people better health information enough to help them act on it?
Women's health is still too often treated as shorthand for reproductive and gynaecological health. The reality is much broader.
A 2026 analysis by the McKinsey Health Institute found that women in the UK spend around 24% more time in poor health than men. Only 7% of women's overall health burden comes from conditions specific to women. Far more, around 60% comes from conditions that affect both women and men but are more prevalent among women.
Cancer, cardiovascular disease, chronic respiratory disease, mental health conditions, musculoskeletal disorders and neurological conditions are all significant contributors to the UK's women's health gap.
Prevention and long-term health management matters. As outlined by the Chief Medical Officer, for adults in the UK, 150 minutes of moderate or 75 minutes of vigorous activity weekly, plus strength training, is recommended for the prevention and management of chronic conditions including coronary heart disease, type 2 diabetes and obesity, alongside benefits for mental health, physical function, muscle and bone strength.
However, knowing what supports our health and being able to apply this to practice are two different things.
That gap between information and action sits at the heart of Fallon Parker's work.
Health doesn't operate in separate boxes
Trilogy Health launched in March 2026, bringing strength and conditioning, nutrition and mobility support into a single platform.
Users can access structured training programmes ranging from beginner to advanced, including running, weightlifting and HYROX strength and conditioning programmes. Nutrition tools include personalised calorie and macronutrient targets, hydration and meal tracking, alongside more than 100 recipes to choose from. The platform also includes more than 14 mobility pathways.
Behind it is Fallon Parker, a registered practitioner on the Sport and Exercise Nutrition register (SENr) who has worked in the field for four years. She has 12 years' experience coaching Olympic weightlifting and strength training and works as a strength and conditioning coach at Leeds Beckett University's Carnegie Sports Centre.
She is also completing a PhD at the University of Bradford exploring physical activity promotion among adolescent girls living in low socioeconomic status communities. But the idea for Trilogy Health came first, shaped by what Fallon was seeing through years of working across nutrition, strength and conditioning and weightlifting.
“The original idea came from my experience working across sport and exercise nutrition, strength and conditioning, and weightlifting. Over the years, I became increasingly aware of how fragmented the health and fitness industry had become, particularly with the amount of information available through social media and online platforms.”
There was no shortage of advice. The difficulty was knowing what to do with it.
“People are constantly exposed to advice about what they should eat, how they should train and what they should be doing for their health, and that information can often be conflicting, overwhelming or difficult to know how to put into practice.”
Trilogy was built around a simple challenge to that fragmentation.
“Trilogy Health isn't simply three separate sections that happen to sit inside one app. The reason I wanted to bring nutrition, exercise and mobility together is because health doesn't operate in separate boxes.”
Information alone doesn't change behaviour
Bringing information together solves one part of the problem. Fallon's research has made her increasingly interested in another: what determines whether someone can actually act on it?
Her PhD focuses on physical activity among teenage girls living in low socioeconomic status communities, particularly the barriers and facilitators that influence their experiences and participation.
“My PhD has subsequently made me think much more critically about accessibility, the barriers people experience when engaging in physical activity and making wider lifestyle changes, and importantly, the fact that simply providing people with information doesn't necessarily lead to behaviour change.”
It is an important challenge for digital health. An app can provide a training programme or nutritional guidance, but information exists within the reality of people's lives. Cost, confidence, time, environment and previous experiences can all shape someone's ability to engage with physical activity and make wider lifestyle changes.
Fallon's research has also pushed her to think about when those relationships with health begin.
“My PhD has also made me particularly interested in how some of these experiences and perceptions begin much earlier in life. If we can create more positive experiences of physical activity and health during adolescence, there's an opportunity for those behaviours and attitudes to carry through into adulthood.”
For women, some of those experiences are shaped by the way exercise and nutrition have historically been presented to them.
Strength, not restriction
Fallon doesn't argue that women automatically need completely different training from men. What she has seen through coaching is that their experiences of exercise and strength-training environments can be very different.
“I've coached women who initially lacked confidence using weights or entering strength-based environments, worried about performing exercises incorrectly or had previously viewed exercise predominantly as a way of losing weight rather than something that could help them become stronger, more capable and more confident.”
It is a distinction Fallon sees first-hand through coaching her women's strength class.
“Seeing someone go from being apprehensive about strength training to becoming confident in what their body can do is incredibly rewarding.”
That shift, from changing how a body looks to recognising what it can do, also shapes Fallon's approach to nutrition.
“I think it's important that we don't place all of the responsibility on women themselves to change their relationship with food and exercise. We also need to consider the environments, messages and expectations that shape those relationships and perceptions in the first place.”
Rather than another cycle of restriction and quick fixes, Fallon wants the focus to move towards what nutrition and movement can add.
“There's an opportunity to shift the conversation towards what nutrition and physical activity can add to someone's life – strength, energy, confidence, physical and mental health, performance and long-term health- rather than continually focusing on restriction or appearance.”
The UK's Chief Medical Officers recommend that adults undertake muscle-strengthening activities at least two days each week, alongside aerobic activity, with evidence pointing to benefits around physical function, psychological well-being, muscle and bone health and the prevention and management of a range of chronic conditions.
Women's health features need to earn their place
Despite Fallon's work with women and adolescent girls, Trilogy Health is not a women-only platform.
There is scope for more tailored support in future, but Fallon is deliberately cautious about adding features simply because women's health is attracting greater commercial attention.
“I'd want any development in that area to be evidence-led and informed by what women actually tell us they need, rather than adding features simply because women's health is becoming a more prominent market.”
It is an important distinction. The women's health gap creates a genuine need for innovation, but putting a women's health label on a product does not automatically mean it addresses that gap.
Recent McKinsey's analysis discusses how solutions need to address genuine unmet need, generate credible evidence, fit into realistic routes to adoption and improve access without widening inequality.
For Fallon, any future women's health development within Trilogy starts with evidence and what women actually need, not a feature designed to follow a market trend.
Building towards more joined-up health support
Trilogy Health currently brings nutrition, exercise and mobility support into the same platform. Fallon wants the relationship between those areas to become increasingly integrated and personalised as the product develops.
“How somebody eats can influence their training and recovery; ongoing challenges with mobility and stiffness can determine how they're able to move and train; and someone's goals can influence the nutritional support they need.”
In five years, Fallon wants Trilogy Health to have developed into an established digital health platform providing support directly to individuals and through partnerships with organisations and workplaces.
“I'd like to see a move away from people having to piece together their health support from lots of disconnected sources. Nutrition, exercise and recovery don't exist independently in people's lives, so I don't think we should always treat them as completely separate areas when supporting someone's health.”
The ambition is not simply to put more health information in front of people. There is already plenty of that.
The harder challenge is making evidence-based support easier to navigate, more connected and practical enough to use in everyday life.
