CHICAGO -- Bally Total Fitness is delaying its sale of the Crunch Fitness chain of 21 clubs, two Gorilla Sports gyms and two Pinnacle Fitness clubs until mid-January. When Bally sold Crunch to Marc Tascher for $45 million in cash, the company said it expected to close the deal by the end of 2005 but instead extended the deadline for closing the deal until Jan. 17.
