A professional dancer turned personal trainer, Izy lives and breathes the health benefits of weight training for women.
As a dancer, she became acutely aware of the struggles women face with body image and the pressure to look a certain way – and has since made it her personal mission to educate women on the importance of strength training.
Whether you’re looking to be challenged or simply build more confidence, Izy brings energy and motivation during every second of your workout – empowering you to be stronger mentally and physically.
Nik’s enthusiasm for exercise and fitness started at an early age. He played rugby (prop forward) for 10 years, before properly getting into fitness at University.
He then worked his way up the career ladder in sports marketing, before deciding to jump ship and swap the corporate 9-5 daily grind for personal training.
From CrossFit coach to Under Armour ambassador, Nik knows how to have fun while taking no prisoners.
Connor’s first foray into sport was a game of football in which he scored an own goal. After being shouted at by his entire team, he vowed never again to play sport and trained as a professional dancer instead.
But, when Chorus Line didn’t give him the attention he craved, he turned to group exercise. With a background in presenting and performing, Connor brings boundless energy to his savage, but fun, classes.
He’ll have you working muscles that you didn’t even know existed, and make you laugh (and cry) like you’ve never laughed befor
Growing up idolising professional footballers and NBA basketball stars it was only natural that Jay chose gymnastics as his sport of choice.
Raised with the ethos of ‘you choose not to be average, so don’t believe that you are’, he joined the illustrious fighting force of the Royal Marines Commandos where his passion for exercise flourished.
With 10 years of service under his belt, and thousands of PT clients – from celebrities to his very own mum – Jay brings an infectious positive energy to help you destroy limitations. Expect to be pushed.
With 13 years of fitness industry expertise, Louis knows a lot about hard work and commitment. A former karate-player-turned-dancer, Louis has a genuine passion for sport and fitness.
He says he dreamed of taking after his dad – who was a Karate Freestyle world champion – but he got kicked so hard he decided to swap his belt and gloves for dancing shoes and the gym.
As a highly-sought-after trainer, he utilises his skills and knowledge to ensure his clients achieve (and succeed) their individual goals.
Want to unlock your full potential and work your body like it’s never worked before? Then Louis is your guy.
Helen brings the energy every single time.
She knows how to ignite the ‘fire in your belly’, she works HARD to get you out of your comfort zone.
Her training style encourages form and quality movement at all times-she really knows how to make you ‘get a movement’. Helen doesn’t take herself too seriously, is playful and genuinely enjoys what she’s doing, which shines through.
Also a DJ, Helen’s playlists are planned to perfection and have been described as legendary ;)
Shannon Belcastro is an Australian singer, songwriter and actress. She is the highest-selling female Australian artist of all time, having sold over 80 million records worldwide. She has been recognised for reinventing herself in music as well as fashion, and is referred to by the European press as the “Princess of Pop”, and a style icon… Oh wait, that's Kylie Minogue.
A 15 year career in the entertainment industry as a Dancer, followed by 10 years in the Fitness industry, Shannon comes with more than enough experience both on the stage and in the gym, and GRNDHOUSE is the perfect outlet for all his worlds to collide.

Now a fitness professional making waves on the London scene, Lauren Naomi will lead you to feel strong, powerful and capable of anything you put your mind to.
She will not only bring relatability, vibes and an infectious smile, but also bags of energy to every session. Get ready GRNDHOUSE!
Fun, fearless and a whole lot of determination, Esmée – known as ‘Essa G’ to her friends – is the epitome of mental toughness.
After being told that she could never walk again, (when a minor surgery took a wrong turn and resulted in paralysis from the waist down), Esmée, despite the odds, taught her body to stand, walk and eventually run.
Since then, she’s completed everything from the London Marathon to an extreme endurance multi-stage ultramarathon in the desert, Ultra X Jordan.
You may recognise her from the reality TV show SAS: Who Dares Wins or from her up-beat online fitness classes on Instagram – either way, you can expect serious high energy and positive vibes.
