Hi! I’m Cristíona, originally from the west of Ireland. My journey has taken me across the world, from studying and working in law, to spending years in modelling, dabbling in acting, and now to where I feel most aligned: mentoring and coaching high-performing individuals to optimise their health, energy, and longevity. I’m a personal trainer, with certifications in nutrition from Cornell University and Health Coaching from the London College of Naturopathic Medicine. I’m also a certified meditation teacher from Alchemy, Bali. My approach blends science-backed strategies with a holistic, personalised method that supports both physical and mental well-being and nervous system health. But the lessons that shaped me didn’t come from textbooks or careers. They came from experience, resilience, and deep personal growth. I’ve loved deeply, navigated challenges, and evolved with every season of life. Divorce, reinvention, and redefining my purpose have taught me that true well-being goes far beyond just training and nutrition. It’s about mindset, self-trust, and long-term vitality. Through it all, I’ve learned this: The most important investment you will ever make is in yourself. This reel is a glimpse into the first half of 2024 - highs, lessons, and the people and places that have shaped me. I’m endlessly grateful, and I know this is only the beginning. If you are ready to step into your strongest, most energised, most confident self - with a coach who understands the nuances of high-performance health, personal training, longevity, and self-mastery - let’s talk. You don’t need another quick-fix program. You need a bespoke strategy that fits your life. 📩 DM me or book a call to find out how we can work together. The best investment you’ll ever make is in your future self.

Sundays are my exhale. I make zero plans (here in Bali at least - no family). Walks, a stretch if my body asks for it, sun on skin, fruit or whatever I’m craving, sea air. A glass of wine… maybe two. Just enough to feel warm, not foggy. I don’t crash into rest anymore. I choose it, so the week ahead feels clean, grounded, and strong. Slow living isn’t laziness. It’s strategy. Rest isn’t my escape – it’s part of my discipline. Long game energy only.

5 things I would love to tell my 43 y/o self: 1. Stop chasing happiness like it’s a finish line. I thought if I just got fit enough, found the perfect partner, got successful enough, “healed” enough - happiness would arrive. It doesn’t work like that. It was never a destination I was behind on. 2. The version of happiness sold to you is mostly about you. True happiness is mostly about everyone else. Every big shift in how I actually felt came from connection, not achievement. Not the goal I hit. The person I called. The client I helped. The moment I showed up for someone. 3. Competing with yourself is still competing. I spent years measuring myself against some idealised version of me - leaner, calmer, more disciplined. That’s still a scoreboard, just a lonelier one. 4. Contribution feels better than accomplishment. A single conversation where you actually helped someone will outlast any personal best you hit alone. 5. Belonging isn’t something you earn once you’re “enough.” I used to think I had to arrive somewhere - a body, a business, a version of myself - before I deserved to feel connected to people. You don’t. That was backwards the whole time. If I could tell her one thing, it’s this: happiness was never something to achieve alone. It was something to build with other people.

My goal at 45 is not to look 35. It is to show you what is actually possible when you take your health seriously. When you lift heavy, eat real food, understand your hormones and prioritise a quality sleep routine. The women I know in their 40s are not declining. They are arriving. They know who they are. They are stronger, clearer and more themselves than they have ever been. We have been sold a story about ageing that simply does not match reality. Muscle is your single biggest longevity tool. Not cardio. Not restriction. Muscle. It protects your bones, your metabolism, your insulin sensitivity and your independence as you age. But I want to be clear. This does not mean you need to live in a gym. Some of the longest lived people in the world do not lift weights at all. They garden. They walk. They move naturally every day as part of a life they love. They eat simply and they are deeply connected to their community. That community piece matters more than most people realise. Yoga classes, Pilates, group training, whatever gets you moving alongside other people. The social connection is part of the medicine. For me personally, lifting heavy is non negotiable. At 5 foot 10 and 68kg I aim for 1.2 grams of protein per pound of bodyweight. That is not an easy number to hit every day. But I know why I do it and I am consistent. I also don’t forget about fibre, and neither should you. It’s what feeds your microbiome and that is the foundation of our health. Find what works for your body, your life and your community. Then be consistent. When it comes to your health, your strength, your energy and your mindset. It is not too late. But if babies are part of your vision, please do not wait. Get your bloods done. Know your AMH. Track your cycle and your ovulation. Understand where you are. Time does matter and knowledge is everything. Chase your strength. Chase your vitality. And if motherhood is your dream, chase that with the same urgency.

I shared this on my stories recently and a lot of women reached out about it, I want to put it here on my main feed as it’s so important and does not get discussed enough. So many young women go on the pill at 16, 17, 18 or even younger. Not always for contraception. Often for skin, for painful periods, for convenience. And then stay on it for 12, 15 years without questioning what it is doing to their body. The problems is the pill masks, it doesn’t fix. For example it can mask PCOS, thyroid issues and endometriosis. You may have no idea if you are even ovulating properly. And when you come off it wanting answers or wanting a baby, you are starting from zero, when it may cost time you do not have. It depletes zinc, B vitamins and magnesium. It damages the microbiome. It elevates SHBG affecting your libido, mood and free testosterone. It has been linked to reduced bone density and increased rates of depression, particularly in adolescents. And here is my bigger question. Women can only conceive for five or six days per month. Why are we flooding our bodies with synthetic hormones every single day for that? To me at this point in my journey that’s a truly crazy concept. To the woman who went on the pill at seventeen and is now in her thirties wanting to come off it. I see you. I know how daunting it feels. But your body has wisdom. And you deserve to know what it is saying. I came off it in my early 30’s because I was tired of pumping synthetic hormones into my body. I wanted to treat my body like a temple. One day I made the decision and never looked back. If you are thinking about coming off the pill and do not know where to start, reach out to me. I am here and I would love to help.

Listen. I am not the skinny girl. I do not regard my body as perfect by any means. But I love it. I love me. If you want the skinny look, with much love, my page is not for you. If you want to gain muscle, be strong, hike mountains without bother, sleep well, regulate your hormones and nervous system, heal your relationship with food, eat your fill of delicious whole foods every single day, and age well and healthily. I am your woman.

Most women working on their hormones are tracking their cycle, prioritising protein, taking supplements and trying to reduce stress. But very few are looking at what touches their skin every single day. I started paying attention to clothing labels the same way I pay attention to food labels. Not because I’m aiming for perfection. But because our overall toxic load is cumulative. The food we eat. The water we drink. The products we put on our skin. The fabrics we wear for hours at a time. It all matters. That doesn’t mean living in fear or throwing out your wardrobe overnight. It simply means becoming a more conscious consumer and asking better questions. When I buy clothing, I look for trusted certifications such as GOTS-certified organic cotton and OEKO-TEX certified fabrics. Transparency matters. Over the last year I’ve gradually replaced many of my synthetic pieces, and personally, I can’t imagine going back. Once you’ve experienced the difference, it’s hard to ignore. Some brands I’ve personally worn and trust include: • Indigo Luna @indigoluna.store • Studio K @studio.k.yogawear • Mate the Label @mate_the_label • Pact @pact I’m not sponsored by any of these brands. I simply wanted to share what I’ve learned so far. I’d love to know: have you ever checked the fabric label on your activewear? And if you have a favourite low-tox or organic clothing brand, share it below. #HormoneHealth #HealthyHormones #HolisticHealth #WomensWellness WellnessCoach OrganicLiving LowToxLiving LowToxLifestyle ConsciousLiving OrganicCotton HealthyAgeing LongevityLifestyle WomenOver40 FitOver40 StrongAtAnyAge HormoneBalance FunctionalHealth BiohackingWomen EndocrineHealth NaturalHealth MidlifeWellness WellnessJourney AgeingWell HormoneFriendly HealthOptimisation
