BOSTON — The International Health, Racquet and Sportsclub Association (IHRSA) is offering a general liability insurance premium credit for all health clubs that employ personal trainers certified by certain accredited organizations.

The certifying organizations must have been accredited by the National Commission for Certifying Agencies (NCCA), which is the accreditation body of the National Organization for Competency Assurance. Those organizations currently include the American Council on Exercise, the National Strength & Conditioning Association and National Council On Strength and Fitness.

The insurer, Philadelphia Indemnity Insurance Co., is providing the discount based on the percentage of NCCA-accredited certified personal trainers on site. Clubs with less than 50 percent accredited trainers on staff are not eligible for the discount. All clubs are eligible to earn up to a 10 percent reduction on their rates depending on the individual state schedule rating plan.

IHRSA has recommended that by January its member club owners hire only personal trainers with certifications from agencies accredited through NCCA or an equivalent accrediting organization.
