The Extensa™ method 

Help your participants get flexible by reducing stiffness and pain, improving sports performance or just getting in better shape.

There are other flexibility instructor certifications out there, but most fall short of providing lasting results because their programs are too difficult for the intended audience. 

We pride ourselves on offering simple and easy to achieve stretching programs. Stretching should be easy and feel good!

Discover the only way to improve and maintain a flexible body. 

Stretching should be simple and feel good!

We're on a mission to debunk the misconception that stretching is painful and difficult to accomplish.


We've learned that in order to create lasting changes the body needs to trust the movements we perform and the positions we get into.


We combine and modify a variety of flexibility techniques and deliver them through simple flexibility training exercises. 


The nervous system calms down and the body adapts to the new flexibility challenges. This create a rejuvenated, flexible and relaxed body.

Instructor Testimonials

What our Extensa instructors are saying

Not only do our instructors love the feedback they receive from their participants but they also love the personal benefits they experience too!

Stretching instructor Cynthia

Extensa Fitness 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.

Flexibility instructor Nathalie

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. A bit like after a massage:) I am used to intense classes, but I chose to do my Extensa training because I needed a class that would allow me to take care of my body... THANK YOU!!!!  EXTENSA
