Blink Fitness, an affordable gym chain with over 100 locations, has filed for Chapter 11 bankruptcy protection to facilitate the sale of the business. Blink received over $20 million in new financing from existing lenders to support ongoing operations pending court approval. Blink, owned by Equinox Group, is pursuing a sale but has provided few details. Equinox, which owns Soul Cycle, Pure Yoga, and Equinox Fitness Clubs, is not listed as a debtor in the Chapter 11 proceedings and isn't expected to file for bankruptcy.
