Owner & Coach

Kenisha Seidel

Hi, I’m Kenisha, the owner of Ultimate Performance Fitness & Nutrition (UPFN). Sport and fitness have always been a big part of my life, and from an early age I knew I wanted to build a career around something I genuinely enjoyed. What I’ve always loved most is being able to help people whether that’s becoming stronger and fitter, improving their sporting performance, building confidence or simply achieving something they didn’t think they could.

My passion for sport led me to study a Bachelor of Exercise & Sports Science, followed by a Master of Exercise Science (Strength & Conditioning). Since then, I’ve had the opportunity to work with a wide variety of people, from those stepping into the gym for the first time through to junior and senior athletes looking to take their performance to the next level.

For the past six years, I’ve worked for myself through KS Performance Coach, building my experience as a Personal Trainer and Strength & Conditioning Coach and developing my own client base along the way. Three years ago, I also began working at UPFN, initially coming on board as a trainer and coach. Over those three years, my role continued to grow as I became more involved in the gym, its members, classes, programs and day-to-day operations.

I’ve worked my way up from running my own small coaching business and working on the gym floor to now becoming the owner of UPFN. It’s something I’m incredibly proud of and a journey that has taken plenty of hard work, learning and growth along the way. Having already been part of UPFN for several years makes taking on ownership even more special, as I’ve been able to get to know the people and community that make the gym what it is.

Moving forward, my goal is to continue building on everything UPFN already represents while bringing my own ideas and experience into the business. I want UPFN to be a place where everyone feels welcome and supported, regardless of their age, ability or training experience, a place where people enjoy coming to train, challenge themselves, connect with others and ultimately achieve their goals.

Fitness was not always part of my plan—until I started at Ultimate Performance and discovered how much I loved it! Once I found my rhythm, I realised I wasn’t half bad at it, and I kept going, even through pregnancy.

I’ve always wanted to help people, but it wasn’t until I joined the fitness world that I found my true calling. Now, as a mum of two, I love setting an example for my kids—they even enjoy joining in when I train! My husband is my biggest supporter, always pushing me to grow and cheering me on through every challenge.

Fun fact: I grew up racing cars, so I know my way around changing a tyre or two! If you’re up for it, maybe I’ll even turn it into a class one day. 😉

I’m so excited to be part of your fitness journey and help you achieve your goals. Let’s make it happen together!

Coach

Amy Courtney

Amy is a women’s health and wellness coach, MumSafe Trainer and experienced fitness professional with a passion for supporting women through the many seasons of womanhood.

With a holistic approach to women’s health, Amy understands that movement is only one piece of the picture. Her coaching brings together strength and movement, nervous system awareness, breath, education and a deeper understanding of what a woman’s body needs through pregnancy, postpartum, motherhood, perimenopause and beyond.

As a mum herself, Amy brings both professional knowledge and lived experience to her coaching.

She believes training should support the season a woman is in, rather than asking her body to constantly push harder.

At the gym, Amy coaches FitMums classes and provides MumSafe training, creating a space where women can move confidently, rebuild strength, understand their changing bodies and feel supported without judgement or pressure.

Her approach is warm, real and deeply individual.

Because women’s bodies change through different seasons, and the way we support them should change too.

My fitness journey actually started right here at UPFN! I began with group training and PT sessions with Luke. Back then, I definitely didn’t expect that a few years later I’d be back on the other side of the room coaching!

Over time, training became about so much more than just going to the gym. It made me stronger and fitter, improved my performance in sport and showed me just how much movement can impact your confidence, mental health and everyday life. For me, fitness has never just been about how you look, it’s about how you feel, what your body is capable of and creating that shift in your mind, body and lifestyle

I’ve been coaching since the beginning of 2023, with experience across 1-on-1 EMS training, group fitness and online coaching. My coaching journey has taken me from F45, to Anytime Fitness and now full circle back to UPFN!

My own journey hasn’t always been a straight line either. I’ve had seasons where training has been a huge priority and others where work, life or injuries have meant adapting along the way. It’s shaped me into a very lifestyle-focused coach. I believe health and fitness should add to your life, not take it over. You don’t need to be perfect, you just need to keep showing up!

Outside of coaching, you’ll usually find me training, running my own business or at a racetrack! I started racing cars at 10 years old and now race Wingless Sprintcars, so sport, performance and a little bit of competition have always been a big part of who I am!

Coming back to UPFN as a coach after starting my own journey here feels pretty special. If I can help someone else become stronger, build confidence, improve their performance or simply feel better in themselves and their everyday life, that’s what it’s all about

Coach

Tiff Henderson

My journey at UPFN started as a 12 week challenger, to a member!

I am now a dedicated fitness instructor, disability support worker and mother who brings a soft and savage approach to training. I aim to push you to keep striving while also keeping you safe!

I balance compassion, consistency and maximum effort. I’m committed to staying strong for myself, my family and my clients, and I focus on purposeful sessions, progressive training and sustainable healthy habits while navigating a busy, active lifestyle. I probably spend too much of my time updating my playlist to get you bobbing your head in between sets, but who doesn’t love a little dance! My passion for women’s health grows by the day and my dedication to gain as much knowledge to utilise for myself, my clients and UPFNs members goals,  will continue to grow!

Fitness has been a big part of my adult life for quite some time now, and I have Ultimate Performance Fitness & Nutrition to thank for that.

When I first started, I had no idea where to begin. Gyms were intimidating and honestly, a little scary. One day, a friend said, “You should come and try UPFN.” So I did. I joined, took part in a challenge, and for the first time I really understood what I needed to do to keep myself fit and strong. They gave me the confidence I needed to eventually go out on my own and work towards my own goals.

Fast forward to now, I have four amazing kids, I’m studying full-time and working multiple jobs. I still absolutely love the gym, but now I get to come back to where it all began and help other people work towards their own goals.

I don’t just want the best outcome for everyone I work with. I want people to feel comfortable, appreciated and, most importantly, seen for who they are. Everyone has their own story, their own goals and their own starting point, and I want to help people feel confident in theirs.

Fitness completely changed my life, and I honestly couldn’t imagine my life without it. Being able to now help others experience that same feeling is something I’m incredibly grateful for.
