North Castle Partners Sells International Fitness

North Castle Partners, the Greenwich, CT-based private equity firm that owns Curves, Jenny Craig and Octane Fitness, has sold Canadian-based International Fitness Holdings Inc.

Details of the sale to TriWest Capital, a private equity firm based in Calgary, Alberta, Canada, were not disclosed in Wednesday's announcement. International Fitness operates World Health and Spa Lady in Alberta.

"Our investment in International Fitness is the most recent example of our successful partnerships in the fitness and recreation sector," Jon Canarick, managing director of North Castle Partners, said in a statement. "We believe the World Health Club and Spa Lady brands are well positioned to continue to provide their members with exceptional health and fitness opportunities."

PwC Corporate Finance served as the financial advisor to North Castle Partners in the deal.

North Castle Partners also announced this week its sale of Ignite, a developer of thermal mugs and hydration bottles, to Newell Rubbermaid for about $308 million.
