Caroline Idiens says strength training has made her more confident at 53 than at 20
The fitness influencer behind viral home workouts credits weightlifting with preserving muscle, protecting joints and easing menopausal body changes for midlife women.
Caroline Idiens, the British personal trainer who gained online renown during the COVID-19 pandemic, says she feels more confident in her body at 53 than she did at 20 — and she attributes the change to strength training.
Idiens, who built a large following with 30-minute home routines known as Caroline’s Circuits, told Women’s Health UK that lifting weights transformed not only her physique but her posture and self-assurance. She said the shift began in her late 20s when she tried a Les Mills BodyPump class and discovered the confidence that comes from being stronger.
Her online community, she said, is made up largely of women in their 40s and 50s who are less interested in chasing a six-pack than in preserving muscle, looking after joints and balancing cardiovascular work with resistance training. Idiens cited concerns common in midlife, including weight gain during menopause and worries about bone health. Osteoporosis, she noted, is a condition characterized by thinning and weakening of bone that can be linked to the decline in oestrogen during menopause.
"It's the first time I'd lifted weights and the thing I loved wasn't just how it changed my physique, but the feeling that I got from being stronger — the sheer confidence it gives you in what your body is capable of," she said in the interview. She added that the improvements show up in everyday movement: posture, the way a person walks and the way they carry themselves.
Idiens said she has been encouraged to see younger women adopting strength training to "future-proof" their bodies. She described watching school-age athletes perform squats, planks and press-ups as part of their conditioning and said it reflected a broader cultural shift toward thinking about muscle mass and skeletal health earlier in life.
When the pandemic closed gyms, Idiens moved her classes online. She said she had to teach herself social media tools, recalling that she once had to learn what a hashtag was, but that the internet offered a way to reach people who might feel intimidated by gym settings. Her sessions are filmed in her family living room and, she said, often feel like "a PT in their sitting room" to participants.
Idiens has more than two million Instagram followers and credited the empathetic tone of her classes for their popularity. She said she shares the experience of midlife with her audience and emphasizes practical goals such as maintaining mobility, supporting bone strength and managing changes that come with ageing.
The full interview with Caroline Idiens appears in the October issue of Women’s Health UK. Her experience reflects a wider, ongoing conversation among fitness professionals and health advocates about the role of resistance training in preserving muscle and bone health as people age.
