About Kathryn Williams: women's fitness and menopause coach

My story

I’m a leading fitness expert with over 30 years’ experience, and I’ve spent my career educating and advocating for women’s health and fitness.

It all started in 1996, when my mum took me to a local aerobics class. From that moment, fitness became my passion, and so did helping women fall in love with movement and positive nutrition.

I spent more than 10 years working overseas, from Australia to Asia, leading fitness, sales and operational teams and spearheading the fitness community. Fifteen years ago, I set up my own business, Zestfit.

Today, I specialise in helping high-achieving women over 40 become the strongest, healthiest versions of themselves and unlock their full potential, with health and wellbeing as the magic bullet.

I’ve had the privilege of coaching thousands of people, both inside and outside the workplace, and I’ve seen the difference it makes to their performance, mindset and overall health. I’m passionate about what I do and proud of it. Nothing beats watching my clients, and the companies I work with, transform their mindset and make long-term health and wellness a priority.

My own experience of perimenopause was messy, confusing and daunting. It led me to educate myself and retrain my body and mind to cope with an endless list of symptoms. Today, changing how women see these challenging years is at the heart of my business.

I’m an Advanced Personal Trainer, Certified Menopause Coach, Corporate Performance Coach and Keynote Speaker.

I live in Derby with my husband, Adam, and our two children, Bella (17) and Ellis (15).

My mission

I believe your health should be the foundation for every other part of your life.

So many women spend years chasing a number on the scales, convinced that confidence, happiness and success are waiting on the other side of it. I see it differently.

This journey isn’t about becoming smaller. It’s about becoming stronger.

Stronger in your body.
Stronger in your mindset.
Stronger in the promises you keep to yourself.

Because when your health becomes a priority, everything else rises with it: your energy, your confidence, your relationships, your career, and the way you show up for yourself and the people you love.

Through personalised coaching, progressive strength training, simple nutrition, accountability and honest conversations, I help ambitious women build routines they can trust and results they can sustain.

This isn’t another quick fix. It’s a lifestyle that gives you the freedom, confidence and strength to enjoy the life you’ve worked so hard to build.

Because the greatest transformation was never the number on the scales. It’s becoming the woman who knows how to look after herself for life.
