Success in collaboration

With a common passion and expertise in group exercise, Marietta and Maria Teresa first met as presenters at a fitness conference in New Zealand in 2009. Although they came from different backgrounds, they soon realised that they had several commonalities and were passionate about group fitness instructor skill development and growth.

Their initial collaboration was in developing a widely successful ‘Watch Your Body Language’ workshop which delved into the importance of non verbal communication in enhancing a member’s experience with exercise. It has helped hundreds of instructors develop an awareness of what is communicated without words can impact rapport and develop long term loyal members.

Their united commitment to change how group fitness instructors are educated and viewed by the rest of the fitness community has lead to several years of working together with respect and integrity which finally resulted in a partnership called MY GROUP MOVE.
