About Jasper MacDermot
Strength, muscle and mobility
that actually lasts
I'm Jasper MacDermot, a personal trainer and strength coach based at UNTIL Liverpool Street. I help people build strength, muscle and mobility so they can look, feel and perform at their best: synergising the most effective principles across multiple disciplines so training stays effective, varied and engaging for years, not months. Across roughly 1,000 clients, from CEOs and senior executives to studios prepping actors, that approach has stayed the same: 1 honest plan, built around 1 person.
Most of the people I work best with are 40-something professionals who are successful in their careers but have trained on and off without getting the results they want: feeling a little stiff, a little weak, carrying some unwanted fat. The fix isn't another 6-week blitz. I ask for a minimum 12-week commitment, training 2 to 4 sessions a week, because that's how long it takes for strength, muscle and mobility to compound into something you actually keep. Most clients stay far longer than that first block.
My edge is the programming: tangible mobility outcomes, high-skill strength expression and muscle gain, combined and progressed deliberately: backed by Functional Range Conditioning and a Precision Nutrition Level 1 certification for the body-composition side. Add genuine rapport and accountability and you get the 1 thing that keeps people training for years. The goal is simple: you wake up in a body that feels good, get dressed without avoiding the mirror, and take pride in how you perform.
