If you are walking by Government Center, you may notice that the former purple corner gym is no longer purple. That’s because the gym (and another location in Porter Square) went from being a Planet Fitness to a new concept called, Rock ‘n Fitness. Aaron West, manager of both locations, says that it was a mutual decision to party ways with Planet Fitness. “We got out of our franchise agreement to open our own entity,” he says. “It was a mutual thing, and it was not easy.” When pressed for more info, West declined to comment.

The new concept has a rock ‘n roll theme (obviously) but will include things that Planet Fitness does not offer, like group fitness classes. “It’s a little more hip,” West says. “A lot of our members were asking for classes.”

The classes will start this summer and will include Zumba, yoga, indoor cycling, and kickboxing. West says that they are renovating and expanding, taking over a downstairs storage room to create the extra space for classes. The pricing will stay the same with the usual $10 a month no contract membership, or clients can upgrade the $19.99 per month membership that provides unlimited use of both clubs, free guests (every time, any person), free stand-up tanning booth use (eek!), and half price off cooler drinks. West says that they plan to open a few more over the next few seasons.
