★★★★★

Really enjoyed this class. It was much more helpful than I had thought it might be. It helped me to feel stronger and to connect breath when engaging the pelvic floor — and banished any fears around what is safe to do in pregnancy.

My Story & Purpose

From grief to strength. From teaching to training. This is how I got here — and why I do what I do.

Following the sudden death of my best friend at 26, I began to use running to help me navigate my journey through grief. I ran my first marathon in 2012, and over the last 12 years I've run 15 marathons and 7 ultras — as well as countless half marathons — raising over £20k for a charity set up in my best friend's memory.

Endurance running became my escape, my freedom, and a way to process things that felt too big for words. In more recent years I found strength training, joining the gym I now co-own in 2020 during covid.

A Shift in Direction

My journey through grief was a key catalyst in my love of exercise — but if I'm honest, at the beginning it was less than healthy. From a potential exercise addiction to a negative relationship with food, I spent years shifting my approach. It was pregnancy and becoming a mum that finally changed things.

Continuing to train during both of my pregnancies was a non-negotiable for me. Training right up until the day I gave birth and returning soon after has continued to support both my mental and physical health — and my mission is to support others to do the same.

Improving Pelvic Health for Women

I am now on a mission to educate and empower women to connect with their pelvic floor and core and prioritise strengthening these key muscle groups both prenatally and postpartum. This is a hugely undervalued, under-researched and under-promoted area of training — and I am here to change that, to support women's overall quality of life and health outcomes post birth.

What I Bring to Coaching

Since becoming a personal trainer, I've developed my own approach — one that supports women in finding strength, confidence, and power through healthy habits that change their lives one small step at a time. I want women to feel safe and empowered to train whilst pregnant. I want mums to prioritise movement as a non-negotiable. And I want to make training challenging, fun, and motivating. I have seen first hand the power of exercise, of doing hard things, of pushing your body, and want to support other women to do the same.

Beyond the Workout

Holistic Coaching

My coaching goes deeper than sets and reps. Movement is one piece of the puzzle — what you eat, how you sleep, your mental health, your daily habits — all of these play a part. Breathwork, nervous system health, nutrition are all part of the work we will do together. The bigger picture is very important to me and I have supported clients through many things — career changes, family and relationships and work ambitions — I'm here for it all!

Pregnant & Strong

45+ guided videos across all three trimesters (with trimester 4 coming soon) — filmed in real time during my pregnancy, designed to help you feel mentally and physically strong throughout yours.

This isn't a workout plan or week-by-week schedule. It's a toolkit to support you in training for pregnancy — giving your body what it needs at every stage. Each workout focuses on building confidence and strength through fundamental movement patterns that can be done at home (or gym if you wish).

The sessions include specific movements to strengthen, activate, and stabilise key muscle groups, such as our pelvic floor, that support our changing bodies. The breathwork and stretching sessions support nervous system health and cultivate calm.

What's Inside

Trimester 1 — Building strength fundamentals from the ground up. These sessions support you developing strength and fitness, as well as building an awareness of your core and pelvic floor and beginning to work on strengthening these muscles in preparation for our changing bodies.

Trimester 2 — Stability, strength and support is the theme of this trimester's sessions — done through full body sessions as well as sessions that specifically target the core and pelvic floor.

Trimester 3 — Honing in on preparing for birth and beyond. We focus on endurance and ensuring the core and pelvic floor is conditioned for what is to come.
