Image Credit: Anna Fowler Today, Gabby is a certified personal trainer, the founder of the Shape Up fitness app, and a fierce advocate for strength - both physical and mental. Her resilience was pushed to its limits on Celebrity SAS: Who Dares Wins, where she proved she's as tough as she is disciplined, winning the shows eight series alongside fellow warrior Queens Dani Dyer, and Emily Seebohm. In our exclusive interview, Gabby opens up about redefining success after fame, building a wellness brand with purpose, and the lessons she's taken from life in the spotlight... Gabby, your app Shape Up is all about female empowerment, which I LOVE! Can you tell me a little bit about what inspired you to create it? Okay, so I've always been really active and into doing regular exercise. I was a professional dancer before getting into the fitness industry, so looking after my body and staying in good shape was just something I had to do. Luckily for me, working out was never something I dreaded - it was actually something I enjoyed, and it never it never felt like a chore... which I know isn't the case for everyone! After completing my musical theatre degree and graduating from college, I did a personal training course and then started teaching dance fitness which I LOVED! During my classes I was able to see first hand what training methods people liked and didn't, and because of that I was able to tailor my sessions to suit them and their needs. So the Shape Up app is almost a continuation of that - it's a platform that helps women transform their bodies through tailored, and encouraging workouts. You recently launched the Shape Up & Reset six-week challenge to help people start 2026 feeling "strong, energised and accountable" - how's it been going so far? It's been really good thanks! I always like to give people the first week of January off, so that they can have a rest and find their feet after all of the madness that goes on over Christmas and New Year's. Having that little bit of a break makes such a difference to people's mental health, and I actually think that's part of the reason why my January challenges always do so well, because when you've have had a minute to reset and refocus, you feel fully charged up and raring to go again! We offer intimate and advanced programmes, so anyone can take part regardless of their ability or levels of fitness, and we're there every step of the way to make sure everyone reaches their goals and targets. You more than anyone will know, social media is a minefield to manage, but I would imagine getting direct feedback from followers and seeing them engage with what you're doing must be a real buzz? Oh it's the best! The community element of Shape Up is literally the driving force behind everything I do! I get so inspired by seeing how dedicated, and focused people are... especially all of the Mums! Honestly, when I see that a busy, hard-working Mum has managed to find the time to get their workout in, on top of everything they have juggle... I just think, if they can do it, I've got no excuse, get to the gym NOW (laughs). You've been so open and honest when discussing the relationship you have with your own body, and like all of us, you admit, you have your off days. What advice would you give to someone who doesn't always love what they see in the mirror? I don't think I know of one single person on this planet who hasn't at one time or another struggled looking at their own reflection in the mirror. It's hard sometimes to adopt a positive mindset about your body and appearance, but, and I hate to say this, that's normal... it feels rubbish, but it's normal, I promise you! I think it's really important to let people know that even though I train regularly, and try my best to eat healthily, there are days when I feel like shit and I don't like how I look. The ethos I like to live by, and what I tell my girls, is that happiness isn't about how we look aesthetically - it's about how we feel within ourselves. And I know that sounds really cliche, but it's honestly the truth. Our long term goal should always be to become comfortable in our own skin, regardless of our supposed flaws. What would you like to achieve this year with the Shape Up app? I'm all about building momentum and spreading the word right now - I want our community to get bigger and bigger! There's strength in numbers, and we can all learn so much from each other. Some of the women we work with have been with us for years - they love what we do, and we love them! I love it when we're all able to get together so I'm working on putting together some more fitness retreats and live workouts - they're
