Isabelle Barter, Founder

Isabelle Barter, founder and owner of Stronger Human, is on a mission to help clients and students discover what is possible.  Isabelle (ever curious and always learning) is a Z-Health® Practitioner, StrongFirst® Level 1 Kettlebell Instructor, Yoga Tune Up® Teacher, E-RYT 200, Functional Range Conditioning® Mobility Specialist (FRCms), and is FMS Certified.

Isabelle’s teaching, coaching, and personal practice are ever evolving, and are centered around exploration, play, dispelling myths, and discovering more effortless and efficient ways of moving.

Her continuing education in the field of neurology for sports performance has lead her to believe that everyone is inherently strong and capable of resilience, everyone is already an athlete, we were all born ready to move!  Some of us just need a little help to fully unlock our movement potential or get through roadblocks that have built up from injury, trauma, or setbacks along the way.

Isabelle helps clients develop physical strength built upon a solid foundation of recovery and restorative practices to allow for long term, sustainable training. She is committed to conscientious ways of moving that value control and functional application to daily life over aesthetics and unquestioned dogma.
