About Jasper Macdermot

I work with people who hold themselves to a high standard in their work and want their body to match it. Often that's a successful professional in their 40s who has trained on and off for years but never quite got the results they wanted — feeling stiff, a little weak, carrying some unwanted fat, and ready to do something about it. Over roughly a thousand clients, from CEOs and senior executives to studios prepping actors, the brief has stayed the same: build a body that looks, feels, and performs the way you want it to.

Everything starts with an honest assessment of where you are, then a programme built around your body and your week. My edge is how that programme is put together: I synergise the most effective principles across several disciplines — high-skill strength, tangible mobility outcomes, and muscle gain — alongside nutrition and lifestyle support for body-composition change. That combination is what keeps training effective, varied, and genuinely engaging for years rather than going stale in months. Load is earned, progress follows capacity, and the plan keeps evolving so it never stops working.

Building real, usable strength. Adding quality muscle that lasts. Mobility and movement — owning the ranges your joints should have, not just stretching into them. Fat loss and body composition through training, nutrition, and lifestyle that actually fit your life. And longevity and performance: staying strong, mobile, and capable for decades, so you perform at your best well beyond the gym floor. The desired outcome is simple — wake up in a body that feels good, get dressed without avoiding the mirror, and take pride in how you perform.

I coach 1-2-1 at UNTIL Liverpool Street and online for people who train confidently on their own. Most 1-2-1 clients train two to four sessions a week on a minimum twelve-week commitment, then roll on from there — significant change takes time, and the clients who get the most out of it tend to stay for years. The relationship matters as much as the programming: strong rapport and real accountability are a big part of why people keep training, and keep getting results.
