Bally Total Fitness is facing a lawsuit filed by a woman who claims she was injured while working out at a Chicago-area club.

Olga Chernyavskaya claims in the lawsuit, which was filed in Cook County (IL) Circuit Court, that a leg curl machine that she was using failed to stop and struck her in the face and shoulder, according to a report in the Chicago Sun-Times. The incident occurred on Sept. 26, 2009, at a Bally in Morton Grove, IL, the newspaper reported.

Chernyavskaya removed her leg from the roller of the weight-stack leg curl machine she was using and kept her hands on top of it to guide it back to its resting place, she claims in the lawsuit. The roller, however, did not stop and struck her in the face and right shoulder, the Sun-Times reported.

The lawsuit claims that Chicago-based Bally and Magnum Fitness Systems, South Milwaukee, WI, the machine’s manufacturer, failed to maintain and inspect the machine and provide adequate safeguards or a safety lock, according to the newspaper. Chernyavskaya seeks more than $100,000 in damages and court costs.

A spokesperson for Bally says the company does not comment on lawsuits as a matter of corporate policy.
