Genuine stories from women who feel better in their bodies—and instructors who now teach with confidence and ease.
“Extensa is a program that over time has given me more flexibility but also better posture and balance. It has allowed me to better connect with my body and have more control over my movements. The dynamic exercises allow me to work in depth, which makes it an even more effective workout compared to the traditional stretching class I attended before I became an Extensa instructor. Teaching it is also a unique experience and participants are very satisfied with the benefits they feel after the class. ”
Cynthia Legris
“I would like to share my experience with Extensa. As an instructor, YES, this is the COURSE I NEEDED to add not only for my clients, but for MY OWN WELL-BEING:) It is SO much more than a simple stretching session. After class, participants often comment on how amazing it is that they got a “workout” at the same time feeling a great sense of well-being...”
