What our certified Extensa™ instructors have to say

Melanie Boucher

Extensa Fitness master trainer

I am so glad to have found Extensa Fitness as I wanted to add a stretch class to my teaching skills. I thought I could probably wing it but in the end I decided to take a certification anyway. And I'm glad I did! After the two day training, I was amazed with how perfect the training was for me. It was more than I expected and I love how the program is flexible and adaptable for the different demographics you might teach. I'm now so much more aware of the importance of flexibility in our day to day life. I've also learned so much about the human body and it's made me a better instructor no matter what format I teach. I loved the program so much I became a master trainer!

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.

Extensa Fitness instructor

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. 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, and I was DOUBLY rewarded because it is also an excellent option to tone all the muscles but in a gentle way:)
