London’s personal training industry is experiencing unprecedented growth in 2025, reflecting a broader national trend towards health and fitness. The UK personal training market is now worth over £800 million, driven by increased health consciousness, demographic shifts, and a strong return to in-person training.
This surge is especially visible in London, where the demand for personalized fitness solutions has led to a boom in boutique studios, specialist gyms, and private training facilities. Independent fitness spaces are thriving, as more Londoners seek customized coaching and flexible, high-quality training environments close to home.
The broader fitness sector is also seeing strong performance, with rising gym membership and increased investment in health and wellness. For Londoners, this means greater access to elite-level coaches, state-of-the-art equipment, and training approaches tailored to every lifestyle and goal.
