Eastern Bloc Training
While working together at SSL, Marv Marinovich and Gavin Macmillan both became deeply educated in eastern bloc training principles responsible for creating many top tier athletes.

Our Philosophy
Where Biomechanics Meets Elite Training
Our philosophy extends beyond biomechanics coaching and into the very way we train. Those same training systems have built hundreds of elite athletes.
Backed by PhD level physios, our story is not just one of athlete rehabilitation, training and performance coaching. It's a journey to the truth of how the human body works, what defines strength and how that translates to sports performance.
We're the best in the world at it.

What we're built on:Eastern Bloc Training
The Spinal Engine
Russian Engineer and Physicist Serge Gracovetsky proved the spine’s role as the primary driver of movement. This became the foundation of our biomechanics approach.
Verkoshansky’s Vision
Verkoshansky said if an inertia machine existed, together with the right understanding of biomechanics, you could create the perfect athlete. We built that machine.

Our Challenge
The Problem: Conventional Weight Training Does Not Translate to Sports Performance
01The Measure of Strength
Weight lifted is only half the equation
When we think of strength, we picture conventional weight lifted as the unit of measurement. If two people can deadlift 500kg, we say they're equally strong — but these contests allow unlimited time to complete the lift. If one person completes it four times faster than the other, is that not important?

02Functional Strength
Strength is orchestrated by the nervous system
Functional strength is a product of muscle action initiated and orchestrated by the nervous system, under highly specific conditions — not simply the load on the bar.

03Rate of Force Development
Force and power, in a fraction of a second
In the majority of sports, it's the ability to produce and control force and power in a very small amount of time. Rate of force development contributes far more to athletic ability than so-called maximal strength. We built the system to measure exactly that.

Recent Outcomes
Aryna Sabalenka
Winning a grand slam
Fixing a champion's serve
Gavin became the biomechanics coach responsible for fixing Aryna Sabalenka's serve, transforming her game and leading to three consecutive Grand Slam victories. The approach combined SSL's unique understanding of spinal mechanics and tendon elasticity.
Now our equipment and modalities are available to everyone.
