Considered training,
for the long term.
Personal training and coaching built on evidence, not noise, for people who take their health seriously.
Enquire“Training here is deliberate. Every session has a purpose and every programme a direction, favouring depth over novelty, and consistency over intensity.”

I came to coaching through my own background as an athlete, and it's shaped everything about how I train clients since.
I now work with clients at KX Private Members’ Club and across Chelsea, South Kensington and North London, building programmes designed for steady, lasting progress.
My approach is grounded in an MS in Biomechanics from the University of Kentucky, alongside over a decade as a competitive diver before moving into coaching.
Before Hedderwick, I coached NCAA Division I athletes as part of the University of Kentucky diving programme, including a South African Olympic athlete through the Paris 2024 cycle, and was part of the staff for the team's first-ever women's SEC Championship.
Alongside client work, I train for the British Stunt Register.
How we work together
Three ways to train, one standard of coaching.
1:1 Personal Training
Fully bespoke programming built around your goals, your schedule and your body. Sessions run at KX, in your home, or at a private studio across Chelsea and South Kensington.
Small Group Training
Structured sessions for two to four, holding the attention of 1:1 coaching alongside the energy of shared work. Ideal for partners, colleagues or friends training toward the same goal.
Online Coaching
Programming, technique review and ongoing support for clients training independently, anywhere. Built for people who want expert structure without needing to be in the room.
Where we train
Sessions are arranged around you, across the following locations.
