Third Space launches Performance Lab for members

Boutique health club operator, Third Space, has begun offering its members science-led assessments to help them identify and reach their health and fitness goals.

The company’s The Performance Lab – which opened in 2025 at its renovated Mayfair club – offers a wide range of analytics, from movement screening, force plate analysis and grip strength to sweat analysis and VO₂ max testing.

“Performance benchmarking used to be something only elite athletes had access to,” said Tim Hart, Head of Performance and Lab Supervisor at Third Space.

“Now, as the awareness of VO₂ max testing has become more mainstream, there’s been a growing appetite for it.”

At the centre of the new offering is the Wattbike AtomX, which not only provides an accurate VO₂ score from the Wattbike Healthspan Check, but once connected to the VO₂ master device at Third Space, is able to provide more in-depth VO₂ max data. Thanks to its ERG mode, theWattbike automatically adjusts resistance to keep power output consistent, giving members precise, reliable data to shape their training.

“Thanks to the Wattbike and our wider testing protocols, every member can access tangible data to understand where they are today and what they need to work on to reach their personal best in the form of a varied, very personalised workout,” Hart added.

As many members have wearables, Third Space is also focusing on personalisation by offering tailored training zones and specific insights into endurance, strength and recovery.
