    Great size great staff and great location! Coming here after visiting the Central one is night and day difference. Bigger, more equipments, and cleaner/newer facility. Shout out to the staff Gabe for making me felt welcome coming to this site the first time. Crowd die down around 7 PM weekday (video taken on Wednesday in Oct) so it’s good that it’s not too crowded. Conveniently located close to T station, many nice restaurants on first floor and next to shopping center. Worth the commute!

    9.25.2025 10:15PM the GYM closes at 12 Planet Fitness 1815 Mass Ave in Porter Square I stopped by to work out at the location above. Let me explain this nightmare and hassle..... At first I had a basic membership. I was told by TYLER I need to spend $5 or switch to their Gym in Porter SQ. I told him I dont need the receipt for $5 he said just in case... the gym is only open for an hour or so .. who's going to harass me to see if I paid??? There is 5 people in the entire gym... Then I told TYLER that I'll just upgrade on my app then and there. The picture attached shows I have a black card now on 9.25.2025. He kept arguing that it may not work on the app because people are complaining about the app. I told him my app in fine. Then I asked TYLER now that I upgraded what gyms am I allowed to use.... He went into the policy and procedures which I didnt ask for. Keep in mind it's 10:30 by this time and they close soon. I walked out PISSED of dealing with being HASSLED after traveling a long distance to work out. Black Card members need some CLEAR information on where they can and cannot work out. Because it states we can use ANY GYM GLOBALLY!!! Please Retrain your people. I removed my information for privacy on my Black Card Membership. See Pictures.

    Been going here for about a year, overall not a terrible gym, but the bathrooms are pretty disgusting. However, in the past month me and my friend have both had money taken from our wallets which were stored in bags in the locker room. Both times this very odd employee (guy literally has no sentient awareness and doesn’t get social cues) was in the locker room when we initially stored our bags inside, so thinking it might be him who ended up stealing from us. In specific, the person who stole from our wallets left our cards behind but took all the cash (around 300 dollars between us).

    It is great! I really like it. It would greatly benefit from having some group classes, such as dance or yoga.
