About Us

House of Unity Fitness was founded by siblings Alex and Tiarna Marek, qualified Personal Trainers with a shared background in competitive sport and more than three years of coaching experience. Both Alex and Tiarna completed their Certificate III and Certificate IV in Fitness, combining formal education with years of practical sporting and coaching experience. Tiarna is also completing a Certificate IV in Nutrition, with additional specialisations in Sports Nutrition Coaching and Health & Wellness Coaching, further strengthening the knowledge behind the House of Unity approach. Together, they created House of Unity Fitness to provide high-quality, purposeful coaching that develops physical and mental ability. Their focus extends to confidence, discipline, resilience, movement quality and helping athletes understand the purpose behind their training. Today, House of Unity Fitness works across primary and high school programs, strength & conditioning, athlete development, sporting teams and club-based training, supporting individuals from their earliest stages of movement development through to more specialised athletic preparation. At the centre of House of Unity, we believe great coaching should meet people where they are, challenge them to grow, and give them the confidence, capability and foundations to keep reaching new levels.

School Testimonials

Broughton Anglican College

Alex and Tiarna from House of Unity Fitness have delivered a highly engaging and well-structured sports program for our Junior School students, from Kindergarten through to Year 6. Their sessions focus on developing fundamental movement skills through fun, game-based activities that keep students active, involved and motivated throughout the lesson. What we have particularly appreciated is the way Alex and Tiarna work alongside our school team. They take the time to understand the individual needs of our students and make thoughtful adjustments during sessions so that all students can participate successfully. This has included tailoring activities for injured students so they can still be meaningfully involved, relocating sessions to alternate indoor or outdoor spaces when needed, and revising their programs at short notice due to weather conditions. Their approach is positive, inclusive and professional, and they have built strong connections with the students in a way that makes each session enjoyable and purposeful. We would happily recommend House of Unity Fitness to other schools looking for a reliable, flexible and engaging sports program provider.
