Tendon Based Movement Biomechanics

Stop mistaking tension for strength. Understand the body you are training.

Your horse works hard. But is that work building a stronger, freer body, or teaching him to hold more tension? This revolutionary book takes you inside Tendon Based Movement. Across 33 chapters, you will understand how muscles work and release, how the back and abdominals cooperate, and why the quality of movement matters more than the amount of effort. Recognise what your training is changing. Know what to develop, what to stop repeating, and when to take a step back. Read this book before you decide your horse simply needs more work.

Who this book is for

Every rider, trainer and horse owner makes decisions that shape a horse’s body. You need to understand what those decisions do. If you want strength with suppleness, a back that moves freely and progress you can recognise beyond a completed exercise, this book belongs in your reading.

01 · What you will learn

01

Understand what muscles actually do in Tendon Based Movement: work when needed, release when the action ends, and coordinate the elastic stride.

02

See why a strong core must still move. Understand how the abdominals support the trunk while the back waves, and why bracing interrupts that cooperation.

03

Develop your eye for the first signs of lost freedom: a shorter neck, uneven back movement, tighter flanks and a change in the horse’s willingness to work.

04

Understand how to develop more movement without simply demanding more speed. Follow the role of conscious relaxation, freer pelvic rotation and progressive conditioning.

05

Make better decisions for the horse in front of you. Understand why an experienced horse still needs time to learn new coordination, and judge progress by how he moves and responds.

From the book

A different task does not automatically create a different movement pattern. A horse can climb a hill or follow a serpentine while keeping the same rigid back. We use variation to develop the movement we have begun teaching through conscious relaxation: a rotating pelvis, a long, waving back, and a relaxed neck. The useful change is how the horse uses his body within the task.

Questions about the book

Why should I read this if I already know the exercises?

Because completing an exercise does not tell you what it is doing to the horse’s movement. He can follow a serpentine or climb a hill while keeping the same rigid back. This book takes you beneath the task: how the trunk is supported, when muscles release, where tension interrupts movement, and what genuine progress looks like. You will understand what you are trying to develop with each repetition.

What does this add to Introduction to Tendon Based Movement?

Introduction establishes the connected elastic movement of the horse. Biomechanics takes you deeper into the body you are training: muscular activation and release, cooperation between the back and abdominals, progressive conditioning, and the signs that freedom is being lost. It connects the movement you see with the decisions you make in daily training.

Is this relevant to a mature horse with established habits?

Yes. An experienced horse can still be a beginner in the movement pattern you are teaching. You will understand why familiar bracing does not disappear simply because you ask for a different outline. The book explains the role of conscious relaxation and growing body awareness, and why short experiences of freer movement need time to become dependable coordination.

Paweł Marciniak

Paweł Marciniak co-founded OneHorseLife and BodyMarc. His work connects physics, mathematics and biomechanics with the movement of horse and rider. He studies how forces travel through the body, how residual tensions change movement, and how the rider’s own coordination affects the horse. Through BodyMarc, he translates these principles into practical work with body awareness and movement.
