How it all began for United By Keren

Keren had been personal training and instructing aerobics in gyms for 11 years and while on a holiday in Hawaii, she heard about the Zumba Fitness program!
She immediately fell in love with program and certified quickly, being a part of the second wave of (40) instructors to be certified across Australia!
This meant that Keren was in the forefront of the game and enabled her to establish herself prominently in the Zumba world of Australia.

Upon certifying Keren recognised the lack of affordable, casual fitness options for people and decided to start up her own ‘ZUMBA with Keren’ business instructing private Zumba Fitness sessions away from the gym setting.
The attendance for Keren’s classes was so high that within 6 months 2 classes per week turned to 12 classes a week and within 12 months there were 22 classes per week on her schedule and UNITED BY KEREN was born. The demand had grown at such a fast rate and it was obvious that people wanted an affordable workout that was fun, professional and still personal. So Keren hand-picked a few of her regular participants who were natural, committed, passionate and excited to help lighten her load. They qualified as instructors and were guided by Keren to present a top-notch, fun and effective class.
Keren continuously strives to offer value-for-money, no strings attached, top quality classes.


My aim is to inspire and assist you to reach your goals and beyond in a fun, non-judgemental party atmosphere. I’ve worked in the fitness industry for over 19 years as a freestyle aerobics, Les Mills, cycle and aqua aerobics instructor. I’ve always managed my own small business, so the personal touch means a lot to me.

  • I am a passionate Cert 4 personal trainer for all populations.
  • I bring this knowledge & all these years of experience to my classes & clients.
  • I thrive on seeing people change their attitude first and then their bodies in turn, making their life much happier and healthier.

I hope that my passion for life, love of Latin music and dance, and my easy-to-follow freestyle moves will engage and push you to your limits in a fun, friendly environment, leaving you wanting more. More importantly I want to know that I have been able to help each and every one of you achieve your goals. Please don’t hesitate to contact me anytime with any questions.
I look forward to seeing you in class soon!

Hi – I’m Clau, I’m a dancer and choreographer from La Paz, Bolivia, and a graduate of the National University of the Arts in Buenos Aires, Argentina. I have been a certified Zumba Fitness and Pilates Instructor since 2015, and during this time I have discovered the power of dance to connect people from different cultures, help them destress, let go, have fun and get fit! I have been lucky enough to teach all around the world, including in Cambodia, Argentina, Chile, Bolivia, Mexico and now Australia ! Each of these places have given me new experiences and new styles of dance, and I have learned a lot from my students as well, that’s my biggest motivation!!


I have been dancing since age 5 and from age 15 I have taught Jazz, Tap, Ballet, Ceroc, Classical, Ballroom, Salsa. I also studied Theater but am now a committed public servant by day & Zumba instructor by night!

Together with my family, we moved to Melbourne in Dec 2017 & joined the United By Keren family almost immediately. I love taking people on musical a journey and I always have a song in my heart.


I absolutely LOVE Zumba! I joined the United family in July 2010 and instructed with UBK until July 2018 when I had a freak accident at a park resulting in surgery and two years off!
I am so excited to finally be back and to be joining you all on the dance floor.

I was a Salsa teacher for 8 years, and absolutely loved the idea of combining Latin dance and exercise. Zumba is the MOST fun workout, it’s easy and the music is addictive. In my early 20s, I traveled and danced my way through South America and Spain and am so excited to bring some of that inspiration to my Zumba classes. Zumba has inspired me and has given me so much passion for exercise, dance and life. I love to teach, and am so excited to share my passion with you!


Yenny brings her natural South American style & passion, along with two years instructing experience. Yenny has blossomed into a fabulous instructor and a very reliable cover to UBK classes. Yenny will jump in when needed to help support the UBK team.
