Technical Mastery & Data-Informed Performance | Rushden, UK | Katie Masters, PhD

Masters in Strength is currently transitioning from general coaching to a more specialist, powerlifting-specific framework. While the sub-pages are being updated for 2026, the Coaching Enquiry system is fully operational. To get in touch, please either use the ‘Apply’ buttons below, visit the Contact Page, or go directly to the Coaching Enquiry Form.

Technical Mastery & Data-Informed Performance

Strength coaching sitting at the intersection of biomechanics, data analysis, competition standards, and psychology. Leveraging a background in Physics, a PhD in Mental Health, and mentorship under Reactive Training Systems to build technical mastery and sustainable progress

Direct oversight from a WDFPF World Champion and International Referee.

Who I Work With

I work mostly with athletes who are plateaued intermediate lifters; they’ve got relatively strong from the ‘usual’ approach – training hard using percentage-based traditional block periodisation – but for whom ‘relatively strong’ is no longer enough.

To go beyond this, my coaching is highly individualised and built from the ground up based on athlete response.

You might be a good fit for this model if:

Competition standards are important to you
You want a ref’s eye on your lifting.
You’re not happy with 2 out of 3 white lights; you want to know exactly why you got a red, and how to structure your training and target weaknesses to prevent it from happening again.

You want a scientific and data-driven approach
You’re interested in optimising your technique based on physics and biomechanics.
You value quantitative tools to help make better training decisions: think custom RPE charts and velocity profiles.

You want a coach who:
Views lifting as being as much mental as it is physical (and you don’t love the idea of dividing a person into mind/body in the first place!)
Can provide a robust conceptual framework based on established principles of strength training that doesn’t ignore subjective feeling, but rather uses it to our advantage to manage fatigue and drive long-term progress.

You value long-term autonomy
You don’t want a coach who will tell you what to do but rather a coach who can give you the tools so that you can start to figure out what to do for yourself.

    The Methodology

    Masters in Strength is built on a unique set of credentials and seeks to optimise performance by combining biomechanics, psychology, and competition-readiness.


    The Biomechanics (Physics): With a First Class degree in Physics, I approach the body as a system of levers with the intention of optimising force production and mechanical efficiency.


    The Psychology (Mental Health PhD): With that said, I completely understand that human bodies cannot be reduced to their constituent parts! Drawing on my academic work in mental health and my own experiences as an international athlete, I adopt a holistic or biopsychosocial approach to the lifter.


    The Execution (The Ref’s Eye): As a WDFPF International Referee, and current Technical Secretary for the BDFPA, I view every rep with the same eye that I use on the international platform. This means that I can identify any potential red lights in your execution (and come up with a plan on how to fix them) so that you can step onto the platform with confidence on competition day.

    The Private Gym

    In-person sessions and Technical Audits take place in my private specialist gym in Rushden. Set in a 1/3 of an acre garden, this offers a quiet, private environment completely free from the crowds, distractions, and noise of commercial gyms.
