How was this counted?
We scanned a 1 km circle around the centre of each area on 13 October 2026 and counted every gym on the map inside it. Places missing from the map or opened since are not counted, so treat the numbers as a floor. Circles of neighbouring areas can overlap, so a place near two centres is counted in both, and the figures are not a total for the whole of Boston.
