What matters here

We meet you
where you're at.

You don't need experience, confidence or a certain level of fitness before you begin. Our coaches give you clear direction, adapt the session to suit you and make sure you never feel like you're figuring it out alone.

Dayna
Manderson.

The person behind the vision—and the standard of care that shapes WITHIN.

Growing up in Rathmines, Dayna wanted to create the local space she always wished was there: somewhere people could train, move and take care of themselves while being surrounded by people who genuinely support them.

Dayna began coaching in 2022. She holds a Certificate III in Fitness, a Mat Pilates certification and the CrossFit Level 1 Trainer credential (CF-L1). Her experience includes building successful youth classes and expanding WITHIN into the Functional Fitness, Mat Pilates and recovery community it is today.

“Our job is to meet you where you're at, coach you properly and help you leave feeling better than when you walked in.”

Her approach centres on clear coaching, appropriate options and helping people build a routine that works outside the gym as well as inside it. She speaks from hands-on coaching and business experience rather than promising shortcuts.
