According to a Consumer Reports survey, some pricey national health club chains don’t fare as well as private yoga, dance or Pilates studios. Gyms at local community centers, schools, workplaces and nonprofit centers (JCCs and YMCAs) also performed better among respondents in the Consumer Reports National Research Center’s first-ever health club survey.The more than 10,000 respondents who had used a gym in the past 6 months reported on staff, equipment, classes, crowds, cleanliness and billing issues. Respondents (3,400) who had canceled a membership during the past 3 years reported on why they had left and whether it was easy to cancel (often, it wasn’t). Among respondents with paid memberships, 16% had encountered a problem with contracts or fees, such as an unexpected dues hike or an inability to freeze a membership during an expected absence. Almost 40% of respondents who had canceled a membership to a big gym had experienced at least one problem; for example, some kept receiving bills after canceling and for others the cancellation process took excessive time and effort.
