Planet Fitness has extended hours at its corporate-owned clubs in New Hampshire to 24 hours a day, seven days a week.

The change, announced on Planet Fitness’ Facebook page and Twitter account last week, affects 11 New Hampshire corporate clubs. The new hours also apply to two Planet Fitness corporate clubs in Massachusetts and two in Rhode Island. The 24-7 corporate clubs are staffed at all hours, says John Craig, director of brand development for Newington, NH-based Planet Fitness.

“Given the 24-7 business cycle and the growing numbers of folks who work second and third shifts, we think it will help a lot of our members,” Craig says.

Most Planet Fitness franchise clubs are open around the clock weekdays until 9 p.m. Friday, Craig adds. On weekends, those clubs are open from 7 a.m. to 7 p.m.
