I’ve loved my time at Built in Boston! Sean and Taylor cultivate a great community vibe, and the space is clean with all equipment in great shape. The trainers place a lot of emphasis on proper form, which makes BIB a great way to combine a small-group fitness setup with personalized adjustments, feedback and motivation. Would highly recommend to anyone in the area!!

Reviews
Sean and Taylor are great trainers. Super welcoming and attentive to your training needs. They’re there to help correct form and modify exercises to increase/decrease difficulty depending on how you’re feeling and your progress.
I started training at Built in Boston because I was tired of working out alone... I wanted an in-person workout community. I am so glad I found Taylor and Sean. They are kind, funny, supportive, knowledgeable, and non-judgmental - they just get it. I look forward to my training session each week.
