Certificate III in Fitness - Alumni

Judy Davenport

I’ve been involved in the fitness industry on a part-time basis since 2008. I started out teaching a Jazz dance (“Aerodance”) class at the Harold Holt Swim Centre (HHSC), Glen Iris. From there, my professional interest in fitness grew. I qualified for my Certificate III in Fitness (Gym Instructor) in 2010 and followed that with the Group Exercise Instructor module later that same year. In September 2010, I completed the Zumba Fitness instructor training and since then have added various Zumba specialty programs to my repertoire. I now teach Zumba Fitness (the "original" program), Zumba Gold-Toning (for active older adults) and AquaZumba. A knee injury sidelined me in Sep 2019 so I concentrated on rehab & recovery for a couple of years before taking up teaching again in Feb 2022. It's great to be back!

Nicky McGowan

Hi! My name is Nicky McGowan & I have been based at Goodlife Springwood since January 2026. I have been in the gym on my own journey since 2012, but most consistently since 2017 and absolutely love working out. I love watching my clients confidence grow, and seeing them do things they didn't know they were capable of. I help my clients by providing realistic plans to fit their lifestyles & help reach their goals. I work mainly with women who are looking to improve their strength, fitness & quality of life. Many women who want to work out to improve their mental health. There are a myriad of reasons to work with a personal trainer beyond aesthetics, and those are the "whys" that I love working with the most.
