Thirty-eight providers span 160 years — from Kings Premier (1857, the second oldest tennis club in the world) to Lifestyle Yoga (2017). Yoga dominates: 18 firms teach it, seven RYT-certified, alongside nine pilates practitioners and nine personal trainers. Two anchor leisure centres — Beau Séjour and Kings Premier — handle the general-fitness load. —
Fifteen studios and teachers, nine in St Peter Port and two on Alderney — Yin and Hatha lead, seven also teach Pilates.
Six trainers on the island — but only four operators. Paul De Garis and Andy Perkins each run two; the other two are sole practitioners.
Four general-fitness sites in Guernsey — three attached to hotels or clubs, one a free outdoor gym in Saumarez Park.
Five Pilates instructors — one Reformer studio (HAY Yoga, Castel), three at All About Yoga, and Sola Movement in St Pierre du Bois.
Eight studios — four ballroom-and-Latin schools, two yoga instructors, the Zumba pioneer, and Wheelchairography.
Three listings, effectively two operators — Andy Perkins's RockFit bootcamps on the west coast, and Jane England's GoYoga timetable.
Three schools — two karate (Guernsey Kofukan since the early 1970s, Alderney Okinawan Goju Ryu) and one aikido in St Andrew.
Three pool venues, all in St Peter Port — the States-run 25m six-lane at Beau Séjour, plus Kings and a hotel suite.
