Tempo Performance operates as a personal training studio in Fitzrovia, one of central London's busier districts where professionals often struggle to fit fitness into packed schedules. Founded by Julian Ernst, the business runs from a private studio space equipped with modern training gear. The setup caters to clients who prefer one-on-one attention over crowded gym floors—think of it as the difference between a tailored suit and something off the rack.

The core offering here is personal training, but the approach goes deeper than just showing up and lifting weights. New clients start with a consultation that covers lifestyle factors, medical history, previous injuries, current eating habits, and work environment. It's the kind of thorough intake process you'd expect from a physiotherapist or sports medicine clinic rather than a typical gym. From there, the team builds out a personalised plan with both short-term milestones and longer-term targets. In my opinion, this level of upfront assessment separates serious training operations from the ones that just throw generic workouts at everyone.

Julian Ernst, the founder, has built his methodology around what he calls a results-based approach. The idea is to strip away overly complicated training protocols and focus on methods that actually produce measurable changes. His client roster includes everyone from people prepping for bodybuilding competitions to office workers who just want to feel better and move without pain. That range suggests flexibility in programming rather than a one-size-fits-all mentality.

Beyond in-person sessions, Tempo Performance offers online and virtual training for clients who can't always make it to the Fitzrovia studio. This hybrid model became more common after 2020, but keeping quality consistent across remote sessions isn't easy. The business has apparently managed to maintain its reputation in both formats, which speaks to how well the programming translates outside the physical space. For anyone traveling frequently or living outside London, this opens doors that wouldn't exist with a purely location-based service.

Strength and conditioning rounds out the service menu, targeting clients with athletic goals or those recovering from injury who need to rebuild functional capacity. The studio also lists rehab work, posture correction, and longevity-focused training among its specialties. There's even a neurotransmitter test available, which digs into the biochemical side of performance and recovery—not something you'd find at your average fitness facility.

Client reviews paint a consistent picture. Multiple testimonials mention long-term relationships with Julian, some stretching beyond three years. People highlight improvements in strength, body composition, and even resolution of chronic pain issues like knee and shoulder problems. What comes through repeatedly is the attention to technique and form during sessions—small corrections that prevent injury and improve results over time. As a reviewer, I notice that clients often mention the nutritional guidance as a key differentiator, suggesting the training extends well beyond the gym floor.

The business philosophy centres on what they call "lifetime value," meaning the goal isn't just to get clients through a few months of sessions but to equip them with knowledge and habits that stick. It's a retention-focused model that depends on actually delivering results rather than churning through new faces. The studio showcases before-and-after transformations on its website, which provides visual evidence of what the methodology can produce when clients commit to the process.

Tempo Performance positions itself in the premium segment of London's personal training market. The Fitzrovia location puts it within easy reach of professionals working in the West End, and the private studio format appeals to clients who value discretion and focused attention. For anyone serious about making lasting changes to their fitness—whether that means dropping body fat, building strength, or addressing movement issues—this is the kind of operation worth investigating.
