Fairfax’s Mosaic District just scored a massive new addition

53,000 sq. ft. for workouts: Onelife Fitness taking over former office space. The concept: less cubicles, more cardio. With boxing, yoga, recovery pods & HydroMassage, this spot is shaping up to be Northern Virginia’s newest fitness anchor.

Whoa. Stunning amount of amenities for Fairfax Residents

  • Large turf areas designed for functional and athletic-style workouts.
  • Outdoor training space with open-air views of the vibrant Mosaic District.
  • Boutique-style group classes, including BodyPump, Zumba, and high-intensity interval training — plus Les Mills and Onelife Signature formats.
  • Advanced cycling studio built for high-energy rides and endurance training.
  • Community lounge areas designed for connection before or after your session.
  • Exclusive Strike Boxing Studio, where expert coaches blend martial arts, boxing, and HIIT-style conditioning.

Is this a new trend alert?

Gyms are increasingly replacing offices across the country — and the Mosaic District might be the blueprint. The shift reflects a deeper change in how we think about workspace, wellness and community. 

With remote- and hybrid-work patterns disrupting traditional office demand, companies and landlords are re-imagining vacant spaces not as cubicle farms but as engines of health, social connection and active lifestyle.
