On the Promenade des Anglais, in the Arenas quarter steps from Nice airport, ON AIR Fitness Nice Arenas offers a concept that contrasts with classic fitness gyms: an underground and industrial atmosphere — exposed concrete, ambient lighting, curated playlist — in a 1,200 m² space well-designed for serious practice.
The gym is organised around several complementary spaces: a cardio-training space with treadmills, bikes and ellipticals, a strength space with machines and dumbbells, a hybrid training zone (functional, kettlebells, TRX, battle ropes), a free weights space for advanced practitioners, and a boxing space with punching bags, gloves and combat equipment. A complete programme satisfying both beginners and confirmed athletes.
ON AIR distinguishes itself primarily through its unique atmosphere — the adjective 'underground' appears in all reviews. The playlist, lighting and décor create a motivating setting that encourages performance. Recent reviews (March 2026) are enthusiastic and specifically mention staff member Samir's welcome, described as particularly warm and professional.
Annual no-commitment membership from €31.96/4 weeks. Trial session available via online reservation. Registration fee €50 + €10/year equipment guarantee.
Highlights: The unique underground atmosphere is consistently cited as what differentiates ON AIR from all other Nice gyms — 'a motivating environment with modern equipment'. Samir at reception is mentioned warmly in several recent reviews. The trial session option before sign-up is appreciated. Boxing equipment is a rare offer in Nice's multipurpose gyms.
Areas for improvement: The Arenas location is off-centre for city-centre residents — ideal for neighbourhood residents and airport-hotel business travellers. Absence of pool or spa space is notable.
Overall: ON AIR Nice Arenas is the finest discovery for underground atmosphere enthusiasts and varied practice — cardio, strength, boxing and functional training in a unique Nice setting.
