The filing, dated January 13, 2026, details a security incident that involved unauthorized access to their systems, which was first identified on July 25, 2025.

As a service provider for various fitness centers, Gym Management Service, Inc. handles sensitive personal records related to member identification, payment processing, and fitness profiles.

While the specific types of personal information affected by this incident were not detailed in the public record, individuals who received an official notification letter from Gym Management Service, Inc. are advised that their data was likely within the compromised systems at the time of the breach. This means that certain personal details you provided to a fitness center serviced by the company may have been exposed.

It is recommended that individuals who received a breach notice remain vigilant by closely monitoring their accounts and financial statements for any unusual activity. Reviewing credit reports regularly can also help detect potential misuse of personal information. If any suspicious transactions or inquiries appear, contact the relevant financial institution or credit bureau immediately.

Consider placing a fraud alert or security freeze on your credit files to help prevent new accounts from being opened in your name without your authorization. Additionally, be cautious of unsolicited communications, especially those requesting personal or financial details, as these could be phishing attempts related to the incident.
