About us

The mission behind the Mom in Balance Workout Program is to help as many (soon-to-be) mothers feel physically strong and full of energy, better equipping them to fully enjoy life. We do this together with a team of motivated and enthusiastic trainers. 


The Mom in Balance Fitness Program was conceptualized by Esther van Diepen (a mom of 4 kids) during the time she spent living in New York, and where she had the opportunity to work with several experts in the field of pregnancy and post-partum fitness. Esther launched Mom in Balance upon her return to the Netherlands in 2008. She collaborated with diverse doctors, experts and organisations while developing the program 

The past 10 years Mom in Balance has been growing rapidly in the Netherlands and we continue to expand to new areas around the world. Each week more than 6,000 women take part in the workouts worldwide. 


Mom in Balance Switzerland

In the summer of 2013 Mom in Balance has been introduced in Switzerland! 

Barbara Rijntjes brought the Mom in Balance concept to Switzerland. In the Netherlands she got inspired by founder Esther van Diepen during her second pregnancy. As a partner of a Dutch consultancy firm finding the right balance between work and family life was a true challenge.  Working out with Mom in Balance during and after her pregnancy has given her the necessary energy for these challenging first years as a (working) mom. Two years later moving to Switzerland for her husbands career has given her the opportunity to re-think her (working) life. Remembering the inspiration Esther has always given to her, Barbara decided to combine her passions and bring Mom in Balance to Switzerland! 

Barbara introduced Mom in Balance to Switzerland in 2013 starting with the Greater Zurich Area. Workouts taking place in Zug, Zurich, Küsnacht and Horgen. In the Summer of 2015 Mom in Balance has started in Basel en Geneva and since 2016 also in Luzern. With an amazing team of trainers and back office Mom in Balance Switzerland is determined to help as many women in Switzerland as possbile. 

Barbara is married to Evert-Jan and has two children: Rose (8) and Tobias (5)
