January is always full of good intentions, but this year something a little more structured — and a lot more supportive — is quietly taking hold across Ireland. The 40 Day Health Challenge, spearheaded by by the team behind Operation Transformation and supported by Ireland’s Classic Hits Radio and The Irish Sun, is already five days in, and for thousands of people it’s become a genuine reset rather than just another short-lived New Year’s resolution.
Running from 5 January to 13 February 2026, the challenge was designed to help people refocus on the basics: eating well, moving more, and looking after their mental health. What sets it apart is that it doesn’t push one quick fix. Instead, it brings together a group of trusted Irish experts to guide people through small, sustainable changes that build over time.
Those leading the challenge are some of the most familiar faces in Irish health and fitness. Personal trainer Karl Henry, GP Dr Sumi Dunne, dietitian Sophie Pratt and clinical psychologist Dr Eddie Murphy have created a daily online plan that tackles physical and mental wellbeing together. Over the course of 40 days, participants follow a programme that blends nutrition, workouts, mindset tools and medical guidance into one simple structure.
Five days in, challengers are already deep into Phase One of their physical training. The resistance and cardio sessions are designed to be accessible, even for people who haven’t exercised in years. Using nothing more than body weight, the resistance workouts focus on building strength, balance and endurance in a way that fits into real life. Every squat, plank and stretch becomes a small win that adds up over the weeks, helping people feel more capable in their own bodies.
Alongside that, Karl Henry’s cardio sessions are giving people a gentle but effective way to get moving. They’re not about pushing to exhaustion, but about finding a pace that feels achievable. As stamina improves, so does energy, and many challengers are already reporting that everyday tasks — climbing stairs, walking the dog, even getting out of bed — are starting to feel easier.
Just as important is what’s happening in the mind. The daily mental wellbeing exercises have been a major focus so far, covering everything from understanding your “why” to the 5-4-3-2-1 grounding technique, perfectionism, neurodiversity and digital wellbeing. For many participants, this side of the programme is proving just as powerful as the workouts. Taking a few minutes each day to slow down, reflect and reset is helping people feel calmer, more focused and more in control of their habits.
The challenge also has a strong community feel. Every week, the experts come together for exclusive video podcasts where they review progress and answer common questions from participants. Whether someone is struggling with motivation, confused about nutrition or just needs reassurance, there’s a sense that no one is doing this alone. Across social media and radio, people are sharing their highs and lows, cheering each other on through the tougher days.
There’s even a health-check element built in. In partnership with Randox Health, lucky listeners are being given the chance to receive a free body composition scan, including their metabolic age — often one of the most eye-opening figures for people starting a health journey. The first of these takes place in Cork on Friday, 16 January, giving participants a real-world snapshot of how their bodies are responding to the changes they’re making.
The journey is being followed across Ireland’s Classic Hits Radio, The Irish Sun, YouTube and social media, meaning everyday people are getting their moment to inspire others while working towards their own goals. It’s not about perfection or dramatic transformations — it’s about consistency, honesty and showing what it’s really like to try and build better habits in the middle of a busy Irish life.
And if you’re only hearing about it now, you haven’t missed the boat. Even though the challenge is well underway, it’s still open to join. For €35, new participants can sign up and jump straight into the programme, becoming part of a diverse community of people from all walks of life who share one simple aim: to feel better in both body and mind by mid-February.
With more than a month still to go, the 40 Day Health Challenge is proving that change doesn’t have to be extreme to be effective. Sometimes all it takes is the right structure, the right support, and the decision to start — even if it’s five days late.
