Sterk Helse

What Sterk Helse does

Sterk Helse & Trening AS is a Norwegian private health and fitness operator founded in 2015, headquartered in Oslo. The company integrates a multidisciplinary clinical practice — covering general practice, sports medicine, physiotherapy, chiropractic, osteopathy, naprapathy, nutrition, and podiatry — with multi-location fitness centres under a single roof. Since 2015 it has grown to four operational centres in Oslo (Nydalen, Hasle, Vinslottet, Løren) and is preparing a fifth, Nadderud, for August 2026. Operations sit under STERK Group AS (org.nr 928 257 622) with three wholly-owned operating entities (STERK Helse & Trening AS, STERK Helse og Trening Hasle AS, STERK Helse AS). Healthcare personnel are authorized by Helsedirektoratet and the company is an Anti-Doping Norway "Rent Senter" member.

The core product surface combines STERK Klinikk (clinic) and STERK Trening (training) with EGYM AI-powered smart circuit equipment, Performance Arena testing facilities, and over 100 monthly group classes (capped at 20 participants). Members are managed through the Go Active mobile app, clinical appointments via PasientSky, and general practice via Helsenorge. Sub-brands include STERK Performance (athlete testing and training) and STERK Restart (12-week lifestyle program). Memberships are sold in three subscription tiers — Base (NOK 599/month), Fleksibelt (NOK 749/month), and Komplett (NOK 1,099/month) — plus ancillary PT (NOK 800–1,100/hr), clinical services, and the Restart program (NOK 9,990–13,990).

The go-to-market is hybrid: direct-to-consumer through four physical centres and the Go Active e-commerce platform, enterprise field sales via a dedicated corporate health (bedriftshelse) team securing employer-paid memberships (Atea, Viaplay, COWI, Aller, Securitas, OUS, Selvaag, Nortura), and partner-channel referrals through 12+ Oslo football clubs (Vålerenga, Stabæk, Lyn, Skeid, Grorud, Oppsal, Kjelsås, FC Oslo, SF Grei, Jar IL, ØHIL, Lyn Toppserie) and the Aktiv mot kreft cancer rehabilitation NGO. Corporate and sports club partners receive 20–30% employee/member discounts under dedicated codes, with portions of fees flowing back to clubs as sponsorship. Revenue is not publicly disclosed, and the company is privately held with no external funding rounds recorded.

Direct peers

• Feelgood Svenska: Feelgood is a Swedish corporate health and wellness provider offering health profiles, training and rehabilitation to employer clients. Comparable to STERK's bedriftshelse (corporate health) B2B motion in Nordic market context.
• Evolve (formerly Elixia): Evolve/Elixia is a long-standing Norwegian fitness chain offering gyms, PT and group classes across multiple locations. Comparable to STERK on consumer fitness footprint and pricing, but lacks STERK's in-house multidisciplinary clinical services.
• SATS Group: SATS is the dominant Nordic fitness chain with deep Norwegian presence, multi-location gyms, personal training and group classes — the closest operational comparable to STERK's multi-site Oslo fitness operations, although it does not operate clinical health services to the same depth.
• EVO Fitness: EVO is Norway's largest low-cost gym chain with a multi-location Oslo footprint. Competes with STERK for price-sensitive gym members in the same geography, although it does not provide clinical services.
• Fresh Fitness Norge: Fresh Fitness operates multiple training centers across Norway with PT-led services. Overlaps STERK on consumer fitness and group training, though with less depth in clinical and corporate health offerings.
• Actic Group: Actic is a Swedish fitness operator with an explicit health-clinic integration (Actic Hälsa), making it one of the few Nordic chains combining gym and clinical services under one brand — a structurally analogous model to STERK's "Klinikk + Trening" proposition.

Emerging players

• Dr.Dropin: Dr.Dropin is a Norwegian private healthcare chain offering GP, specialist and mental health services with strong digital booking. Comparable to STERK's clinical side on patient-facing private healthcare in Norway.

Regional players

• Stamina Sport och Hälsa: Stamina operates Swedish fitness centers with explicit health and rehabilitation integration. Conceptually similar integrated gym-plus-health model to STERK but operating in Sweden rather than the Norwegian market.
• 3T (Trondheim): 3T is a multi-location fitness and performance operator in Trondheim with integrated physiotherapy and performance training. Highly comparable business model to STERK but based outside the Oslo region.

Broad incumbents

• Volvat Medisinske Senter: Volvat is one of Norway's largest private medical clinic networks offering physicians and specialists across multiple sites. Overlaps STERK's clinical (physiotherapy, sports medicine, GP) services in the same Norwegian market, though it does not operate gyms.
