About SUNI
Shine Under New Intensity.
That's not just our name. It's our philosophy.
At SUNI, we believe your body adapts and improves when you challenge it with greater intensity not recklessly but purposefully. Increase the load. Raise the heart rate. Push a little harder than last time. And watch your body respond: growing stronger, building muscular endurance and boosting cardiovascular health.
We're here to empower you through that process.
What We Offer

Our Why
Fitness isn't about perfection. It's about adaptation. Every workout is an opportunity to meet a new intensity level and to shine through it.
About Penny
Hi I’m Penny, the owner of SUNI. Thank you for visiting my website. I created SUNI as I am on a mission to empower people to be strong and push themselves out of their comfort zones. I first trained as a gym instructor in 2017 where I taught aqua and circuit classes. This is where I fell in love with empowering people to get fitter.
I re-trained as a gym instructor in 2025 to refresh and update my knowledge so I could again help people to get fit. Working out has personally helped me so much with my mental and physical health so I would love to continue to help individuals reach their goals and have a good time whilst achieving it. I genuinely care about people's wellbeing and I really believe that being strong matters.
