The listing name here reads "Pretty Girls Train Fitness Studio," but every reviewer calls it TRAIN Fitness Studio, or just TRAIN. So if the sign out front and the reviews seem to disagree, that's the reason. It's a personal-training and small-group fitness studio in Boston's South End, tagged as a yoga studio and fitness center, sitting at a 5.0 across 74 ratings. That's a high score on a decent-sized base, and I'll explain what's holding it up and what it's quietly leaving out.
What people describe
This place lives on named coaches and one-on-one work. A January 2026 client trained for a specific goal: "I trained with Brian to get in shape for my wedding and couldn't recommend him more! He's extremely knowledgeable about fitness and nutrition, and he helped me gain confidence in the gym. The studio is always clean, well-equipped, and welcoming." A May 2026 review followed a different coach: "Tara is a great coach and she has been really helping me improve my fitness. She makes me look forward to working out and building my strength." A June 2026 note named a third: "Christian has been amazing! Comprehensive exercise programs, thoughtful coaching, and all around incredible trainer!" Three different coaches, three happy clients. That breadth matters, because it suggests the quality isn't riding on one person.
The studio also hosts group events. A November 2023 review described a partnership: "TRAIN studio was absolutely incredible! They hosted three sessions of shadowboxing for Northeastern CHAARG, which is a women's health and wellness organization. Gabi, our instructor, was a Northeastern alum who made the environment incredibly welcoming." So it does external group sessions on top of individual training.
What the 5.0 is measuring
Here's the honest read. This is a coaching studio, and coaching studios post high ratings because clients who bond with a trainer come back and rate warmly, while a poor fit usually just doesn't sign up again. The score is real, but it's selective. You're buying a coach relationship and structured programming, not a walk-in gym floor you use alone. Even the one four-star in the set, from September 2025, is glowing: "The energy is always positive, the workouts are challenging, and the coaches really know how to push you without it feeling overwhelming." When your lowest visible review still reads like praise, the sample is self-selecting toward people who committed.
What's missing
No review states a session price, a package rate, or whether you can drop in without a coach. The posted hours are wide, 5:00 to 22:00 every day, but nothing confirms whether that's staffed training time or open access. For a studio built on personal training, cost is the first thing I'd ask, and the reviews leave it blank.
Who it's not for
Anyone wanting a cheap, self-serve gym to swipe into and lift solo. This is coach-led training and small groups. If you don't want a trainer involved, why pay for a studio built around one?
