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.”

Founder profile

Coaching experience.
Community perspective.

Dayna is the owner and Head Coach of WITHIN. Coaching since 2022, she holds a Certificate III in Fitness, Mat Pilates certification and CF-L1. Her experience spans adult group coaching, beginner support, youth fitness programs and building an inclusive local training community in the suburb where she grew up.

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.

Meet
Kendyll.

Professional yapper, part-time fitness enthusiast and full-time believer that every problem can be solved with a yarn and a coffee.

Kendyll holds his CrossFit Level 1, has further fitness qualifications in progress and is studying Community Services. Outside the gym he's a Cultural Mentor with Aboriginal youth programs, still willingly plays rugby league on weekends and generally says yes to things before checking his calendar.

His training philosophy: lift heavy things, move reasonably fast, train with purpose, keep it varied, challenge yourself and build fitness that actually carries over into life. And occasionally question why we voluntarily pay to do burpees.

Ask him about college football, CrossFit or whatever he's become an expert in after 45 minutes of doom scrolling. All media enquiries are forwarded directly to his wife.

Meet
Alex.

Try it, see if it works, and if you don't get injured, rinse and repeat until the results change.

Alex brings practical coaching and a very dry sense of humour to the WITHIN team. Before moving to Australia he did a stint at Edinburgh Zoo as the “Penguin Erector”: when planes flew over, the penguins would stare up, topple over backwards, and Alex would stand them back up.

His areas of expertise include old Toyota LandCruisers, Warhammer models, British history and Vegemite spoons. Favourite media topic: penguins. Credentials include Blockbuster Video Manager of the Year, 1999. All media enquiries go through his agent, Jay.
