KB Pre & Postnatal Fitness
Motherhood is a profound transformation.
Whether you are currently growing a tiny human or navigating life with one in your arms, your body, energy and priorities are evolving.
At KB Fitness, we are here to support you through every stage of this chapter helping you maintain your vitality, restore your core and build a body that feels strong and capable.
This isn't about "getting your body back"; it's about honouring the body you have now. Our program is designed to meet you exactly where you are:
Prenatal Support: Focused on functional strength, pelvic floor health, and preparing your body for the physical demands of birth and beyond.
Postnatal Recovery: A gentle, step-by-step guide to rebuilding your foundation, regaining core stability, and boosting your energy levels.
Sustainable Strength: Whether you’re managing a bump or a toddler, we provide the tools to help you feel confident, resilient, and empowered in your movement.
Every journey is unique. Let’s take the next step together.

Meet your coach, Kirst! ✨
Welcome, I’m Coach Kirst!
I’ve been a qualified personal trainer since 2020, but everything changed for me when I became pregnant with my son in 2023. Suddenly, I found myself searching for clear, supportive and positive guidance on how to move my body safely during pregnancy… and realised quickly just how limited that support really was.
That experience reshaped my purpose.
I decided no woman should have to navigate this chapter feeling unsure, overwhelmed or alone. We needed better information, better support and space where they could feel strong, confident and truly seen. So I completed my pre and postnatal training and began reshaping the way I coached.
Two years later, I’m the strongest, fittest and most empowered version of myself, not just physically but mentally. And that’s exactly what I want for every mum I work with.
Through KB Fitness, my mission is simple:
to guide women through pregnancy, postpartum and every stage beyond, helping them rebuild strength, restore confidence and feel energised in their own bodies again.
Whether you’re six weeks or six years postpartum, you deserve support that meets you where you are. No pressure. No judgment. Just a warm, welcoming space to grow, move and feel good again.
I’m here to support you every step of the way because motherhood may change everything, but it doesn’t mean you stop being you!

"I'm writing this at 6 months postpartum and have been working with Kirst since i was 12 week postpartum. She has put together enjoyable, easy-to-follow workouts.

"Being able to exercise and move my body through my pregnancy has been SO good for me. Kirsten has been amazing supporting my fitness since 9 weeks pregnant, creating bespoke plans around my schedule, checking in regularly and being able to guide me whether I’m working out at home or in the gym! Kirsten cares so much about her clients and with her knowledge and expertise as a mum herself I can’t recommend signing up with her enough!"
