4D High Performance Program
Managing athletes across multiple disciplines and all competition levels within 4D's High Performance program — designing and delivering individualised S&C programs in a performance environment.
Jack's approach.
The 4D system.
Every athlete Jack works with follows the same structured pathway — thorough assessment, individualised programming, coached execution, and performance outcomes.
Movement & Capacity Screening
A thorough assessment of your movement quality, strength baseline, and athletic demands — laying the foundation for programming that's actually built around you.
Individualised S&C Programs
Programs designed around your sport, your position, your training history, and your goals — informed by ASCA Level 2 expertise and real-world elite coaching experience.
Coached Execution
Hands-on coaching with technical cueing, load management, and progressive overload — the same standard Jack brought to national academy environments, applied to your training.
Competition-Ready
Stronger, faster, more resilient — and built to perform when it counts. Jack prepares athletes for the demands of their sport, not just for the gym.
