"The incredible coaches and members at Treign have smashed any negative feelings I've help for years against gyms and training"

Small Group Classes

We like to keep it personal and technique is important to us. Our small group style sessions ensure you get the individualised attention you need with the added bonus of an epic cheer squad!


Specialty Training

Think of these classes as the polka dot dress in a closet of suits. The staples are important – but the special things keep it FUN! Our speciality classes focus on other areas of fitness that help us improve our skills, learn new things and mix it up!


Personal Training

Need a bit more personalisation? Girl, we got you. Whether your goal is weight loss, muscle, or maintenance our coaches will work with you individually to create sustainable lifestyle habits that set you on the right path for life. We’re all about finding the right approach for YOU … not moulding your lifestyle to fit our expectations
