<\/p>\n But what many people don\u2019t realise is that Caroline didn\u2019t set out to become a global fitness figure. Before all this, she was clocking up cardio sessions between long days in advertising, later retraining as a PT where she grafted away in parks, school halls and living rooms long before Instagram ever met her. Then came lockdown, and the small Zoom class that unexpectedly changed everything.<\/p>\n You may like<\/p>\n To me, she\u2019s proof that you don\u2019t need a studio, elaborate kit or endless hours to get stronger, and that crucially, it is never too late to start.

At school, it was hockey and running, but once the school day ended, I would spend every minute with my horse.\u201d<\/p>\n \u201cBut it wasn\u2019t until my late twenties that I was introduced to lifting weights. Before that, fitness in my twenties was very cardio-based – I loved HIIT, but I also did a lot of running and spin classes. Then I discovered Body Pump, fell in love with strength training and from there, it became the focus of my training.\u201d<\/p>\n \u201cOutside the gym, though, life looked very different. I was still working in advertising and strength training with my own PT. I loved my job, but I always felt like there was something missing.\u201d<\/p>\n \u201cSeeing how my strength sessions not only transformed my body, but also my inner confidence and strength, totally changed how I viewed my whole routine. That feeling of empowerment, strength and improved overall wellbeing was something I wanted to share with others.\u201d<\/p>\n \u201cSo, in 2001, I took the leap and decided to qualify as a PT in order to deepen my knowledge, from nutrition and sports rehab to pre- and postnatal exercise. And that\u2019s when things really started. I started my PT business in London, working one-to-one with clients in parks across the city.\u201d<\/p>\n You may like<\/p>\n \u201cThen our lives changed when we had children, and we moved out of the city to the countryside, where I began teaching group classes to the mums at school. We\u2019d often have 20-30 mums at any one time, and the local community around my classes really grew.\u201d<\/p>\n \u201cLockdown was pivotal, as that was the moment that Caroline\u2019s Circuits<\/a> was informally born. All of my local clients had been lifting weights for years with me at that stage, and they were very keen that we kept it going across a screen whilst we were all at home. Not only did it give us a community in those times, but the group started to build very quickly.\u201d<\/p>\n \u201cCaroline\u2019s Circuits was the name one of my clients gave to our Zoom sessions, which took place three times a week at 9 am. It\u2019s lovely because the times we train remain the same today, but now it\u2019s not that little group of 40 of us on Zoom, but a global online community with classes that can be accessed anytime, anywhere.\u201d<\/p>\n \u201cInstagram was where Caroline\u2019s Circuits really took off. I was using it to share free workouts<\/a> and to promote my online platform, and was really learning as I went along. Then one day, whilst I was away teaching on a retreat in Tuscany, an American home workout company shared my reel. It was an upper body workout – I had around 15,000 followers at the time, and it started to grow at a crazy rate. The rest is history.\u201d<\/p>\n \u201cWhat struck me most was the global connection. People from all over the world were working out together, improving their strength and focusing on their long-term health. It made me realise just how powerful a sense of shared motivation can be, even through a screen.\u201d<\/p>\n \u201cOf course, it\u2019s different from working one-to-one or in person with clients. But that\u2019s why the engagement and interaction with my community is crucial. I\u2019m still the sole manager of the Instagram account, and I\u2019m there to help and guide, from sharing technique and form tips to advising on weights and trainers.\u201d<\/p>\n \u201cA lot of my content is driven by what my clients and followers are asking, which in some ways gives it a different kind of intimacy than my one-to-one sessions. Women reach out with questions like \u201cHow do I modify this move?\u201d \u201cI can\u2019t do a press-up. Where do I start?\u201d, or a common one is, \u201cI\u2019m new to strength training, is this for me?\u201d – it\u2019s really special to be able to support them from wherever they are in the world.\u201d<\/p>\n \u201cEarly on, I made the conscious decision not to create a sleek studio vibe. I want people to feel that they have their PT with them in their living room. I\u2019m there too, with no fancy equipment, just dumbbells and resistance bands, and often training with the chaos of dogs, deliveries and family in the next room.\u201d<\/p>\n \u201cFor me, being relatable and approachable isn\u2019t a marketing ploy; it\u2019s how I train. I\u2019m the same age as many of the women joining in, we\u2019re in it together, and I believe that\u2019s what builds trust and long-term connection, because it\u2019s real. Even if you\u2019re time-poor, juggling work, family, or feel intimidated by conventional fitness culture, you belong here.\u201d<\/p>\n \u201cI still love the feeling I get when I teach a class. It totally transforms my mood, and knowing that the workouts are helping people to stay strong, to support their bones and muscles, improve their posture, and feel mentally better is a huge motivator.\u201d<\/p>\n \u201cI do think conversations around fitness are changing for the better. It\u2019s not about chasing an aesthetic, it\u2019s about building strength, resilience and longevity, and about feeling confident and capable as we age.\u201d<\/p>\n \u201cThe most important realisation I help women make is that it\u2019s never too late to start, and that ageing doesn\u2019t have to mean weakening. Movement is a lifelong ally, and what we do today can impact our quality of life for decades to come.\u201d<\/p>\n \u201cI hope people finish my sessions feeling strong, not just in their muscles but in their mind too. They should feel energised and proud of what they\u2019ve completed.\u201d<\/p>\n Caroline’s 10 strength training tips for beginners:1. Incorporate strength, not just cardio<\/p>\n When people think of exercise, they often gravitate straight to cardio. But in Idiens\u2019 opinion, it\u2019s better to take a strength-first approach. \u201cStrength and cardio aren\u2019t mutually exclusive,\u201d she says, \u201cbut resistance training is the foundation of muscle, bone density, posture and mobility – all especially important as we age.\u201d<\/p>\n A baseline of strength helps you maintain good form, recover well and stay injury-free across all forms of movement. \u201cUltimately,\u201d says Idiens, \u201chaving a balance is how we get the best results.\u201d<\/p>\n 2. Chase consistency, not perfection<\/p>\n We\u2019re huge fans of exercise snacking here at Marie Claire UK, and Idiens agrees. \u201cEven short sessions of 20\u201330 mins, done regularly, beat sporadic over-intense workouts,\u201d she assures.<\/p>\n Research backs this up: one study<\/a> published earlier this year found that just two challenging sets per session, and four to six sets per week, may be enough to build noticeable strength. Idiens adds, \u201cYou don\u2019t need to train for an hour – those small, consistent efforts accumulate.\u201d<\/p>\n 3. Focus on functional movements<\/p>\n Functional training has exploded in recent years, but Idiens has been championing it long before it was a trend. Simply put, it means choosing exercises that support everyday life. \u201cSquats, lunges and press-ups build the strength you need for real-life tasks, from carrying to improving balance and posture,\u201d she says.<\/p>\n And the science? A 2021 study<\/a> found that those who followed a functional strength programme improved their movement score by nearly 20% in eight weeks, compared with just 2% in those following traditional strength training.<\/p>\n 4. Stick to manageable equipment<\/p>\n This one\u2019s a firm favourite. It\u2019s easy to think you need to spend money to get stronger, but as Idiens reminds us, you can get an effective workout with minimal kit. \u201cDumbbells, resistance bands or even body weight can work,\u201d she says. \u201cThe key is having some resistance to work against and gradually increasing your load as you get stronger – something we call progressive overload.\u201d<\/p>\n 5. Don’t be afraid to modify<\/p>\n Many people assume the most advanced version of a move is the only one that counts, but that mindset can stall your progress. Modifications exist for a reason – they help you build up to the full movement safely.<\/p>\n \u201cTechnique is everything,\u201d says Idiens. \u201cIf you can\u2019t do a full press-up, start against a wall or on an elevated surface. If a move feels too hard, scale it back. Do what\u2019s right for your body now, not what you think you \u2018should\u2019 do.\u201d<\/p>\n 6. Prioritise your sleep, recovery and nutrition<\/p>\n \u201cStrength training works best when you support your body with good sleep and fuel,\u201d says Idiens, who is clear that results don\u2019t come from the workout alone. Stress, hormone health, food choices and sleep quality all play a role.<\/p>\n \u201cProtein is especially important for muscle repair and growth,\u201d she says, \u201cbut really it\u2019s about aiming for an overall balance that\u2019s positive and sustainable for you.\u201d<\/p>\n 7. Be patient – results take time<\/p>\n Social media may love a quick fix, but in Idiens\u2019 experience, meaningful changes take time. \u201cMost clients feel changes within a couple of weeks,\u201d she says. \u201cTangible improvements in strength usually show within a month, and long-term habits start forming around six weeks.\u201d<\/p>\n Everyone progresses differently, but the message stands: stay consistent. Changes are happening, even if they aren\u2019t immediately visible.<\/p>\n 8. Focus on what your body can do, not just how it looks<\/p>\n Exercise offers far more than physical changes. It boosts confidence, improves mood, strengthens focus and supports long-term health. Idiens encourages celebrating those wins just as much as any PB.<\/p>\n \u201cCelebrate strength, flexibility, mobility, energy and the inner confidence resistance training can support,\u201d she says.<\/p>\n 9. Make fitness integrate with life<\/p>\n The best habits are the ones you stick to, which is why exercise should blend into your life rather than feel like another task on an already packed schedule.<\/p>\n \u201cIt\u2019s about sustainable habits, not an overhaul,\u201d says Idiens, who\u2019s a huge fan of fitting workouts around your day – whether that\u2019s a hotel room, a lunch break or your living room.<\/p>\n 10. Be kind to yourself<\/p>\n \u201cStrength training should feel empowering,\u201d concludes Idiens. \u201cFind movements you like, work at your pace, and appreciate how your body responds.\u201d<\/p>\n Shop MC-UK Approved Strength Training Kit Now: \n <\/a><\/p>\n Sweaty Betty Stamina Seamless Sports Bra<\/p>\n Seamless, unpadded and with a ribbed underband, this sports bra hits the sweet spot between comfort and support, making it perfect for low-impact strength sessions.
