Marc Tascher, who was named president and CEO of Bally Total Fitness last September, has resigned.

Tascher told Club Industry in an email that he resigned last month "to pursue other opportunities."

"While there, I had the pleasure of working with a great team and I am very proud of our accomplishments," Tascher said in the email. "Together we developed and executed an operating plan and achieved unprecedented sales and revenue growth, exceeding everyone's expectations. Bally is poised for success and is in very capable hands."

Tascher adds that when he accepted the offer to be CEO, both he and the Bally board of directors agreed that it could be a short-term appointment.

"The smaller company needed a plan, and my initial goal was to develop and launch this plan," Tascher said. "After a successful launch, I had a decision to make, and I decided that the timing was right for me to depart."

Tascher did not say who has filled his positions at Chicago-based Bally.

Tascher, who also served on the Bally board, took over for Mike Sheehan, who had been Bally's CEO since 2008.

In 2005, Tascher and Angelo Gordon and Co. entered into an agreement to purchase Crunch, New York, and its 21 clubs from Bally for $45 million in cash. Tascher was named the chairman and CEO of Crunch after the acquisition was finalized in January 2006, but he stepped down as CEO six months later.

Earlier in his career, Tascher co-founded and later served as chairman and CEO of Town Sports International (TSI), New York, which operates New York Sports Clubs, Boston Sports Clubs, Washington Sports Clubs and Philadelphia Sports Clubs. After 22 years at TSI, Tascher sold the company and built Sports and Fitness Ventures.

Since 2006, Tascher has owned, operated and provided management and consulting services to other fitness clubs.

This is another change for ever-evolving Bally, which sold 171 clubs to LA Fitness in 2011 and 39 clubs to Blast Fitness in 2012. In a recent press release about a mobile fitness partnership, Bally said it was now operating 44 clubs in New York, New Jersey, California and Colorado.
