F45 Training One Tree Hill is a functional group fitness studio on Princes Street in Onehunga, offering reimagined group fitness classes rather than a traditional gym setup. The studio draws on F45's library of over 5,000 dynamic, energy-packed movements and more than 80 workouts, combining the effectiveness of a certified personal trainer with a team training environment.
Classes cover a range of formats including cardio, resistance, hybrid and recovery sessions, alongside F45's HYROX training, PEAK500 and LIONHEART programs. The studio is run day-to-day by trainers including Aimee Rowe and Bana Meleisea, with the studio's owner also serving as studio manager.
Members consistently describe F45 One Tree Hill as a genuinely welcoming, community-driven space — trainers tailoring workouts to individual needs, a well-maintained facility, and a culture built around encouragement rather than intimidation. The studio also runs a recovery offering and a members' challenge program, and welcomes both locals and visiting members from other F45 studios.
On Princes Street in Onehunga, F45 Training One Tree Hill offers a reimagined take on group fitness — team training built around the effectiveness and attention of a certified personal trainer, delivered in a class setting rather than a solo gym floor. The studio describes itself as more than a gym: a total wellness solution built for every body.
F45's program draws on a library of more than 5,000 dynamic, energy-packed movements across over 80 different workouts, giving members genuine variety rather than repeating the same routine every visit. At One Tree Hill, that includes cardio, resistance and hybrid class formats, dedicated recovery sessions, and access to F45's specialty programs — HYROX training geared toward the HYROX fitness racing format, along with PEAK500 and LIONHEART. The brand notes it has been rated the #1 gym by Men's Journal in the US and Canstar Blue in Australia.
The studio is run by a team including trainers Aimee Rowe and Bana Meleisea, with the studio's owner also serving as studio manager. Members consistently describe the coaching as genuinely tailored — trainers adjusting exercises to suit individual ability and goals rather than running a one-size-fits-all class, and building a level of familiarity where, as one member put it, staff know your name and you know theirs.
What comes through strongly in member feedback is the sense of community at F45 One Tree Hill. Members describe a welcoming, encouraging atmosphere well suited to people who've felt daunted by traditional gyms, with the studio's culture built around support rather than judgement. Success stories shared by the studio include members establishing their first sustainable fitness routine, focusing on resistance training for the first time, and building consistency and confidence through the studio's community and coaching rather than needing to "love the gym" from day one.
The studio also runs the F45 Challenge, a structured program members can join to work toward specific goals with added accountability and support. Feedback from members repeatedly highlights the space itself as large and well maintained, and the studio has also attracted visiting members from other F45 locations, including international members who treat it as their home studio while in Auckland.
