# Built X3 - Female Personal Trainer, North London

Built X3 is a personal training business based in North London, operating from Parkview Health Clubs in Palmers Green and other local gyms. Founded by Thea Scarlett-Lawrence, a trainer who lost 42kg over six years, the business specialises in transforming clients' bodies and mindsets through personalised fitness coaching.

The business serves women seeking comprehensive body transformation, whether aiming for weight loss, strength building, or confidence development. Thea works with clients at all fitness levels, taking a flexible, supportive approach that prioritises education alongside physical results.

What sets Built X3 apart is its integrated app platform, which extends training far beyond gym sessions. Clients gain access to video workouts, personalised programmes with specific rep and weight recommendations, nutrition tracking, meal plans, habit and goal monitoring, and progress diaries. This technology-enabled approach allows structured, organised training with continuous accountability and communication between sessions.

The business emphasises sustainable transformation over quick fixes. The signature 12-week programme combines initial consultation and compatibility assessment with progressive weekly development of strength, shape and confidence. Thea positions herself as a mentor who challenges thinking patterns, navigates client fears, and maintains flexibility throughout the journey—drawing on her own experience of setbacks to provide genuine understanding and support.
