    I've been training at BIB, twice a week, every week for about a year. I had never done training before this.

    I really appreciate the thoroughness of my workout plan and the real time adjustments incorporating my feedback when something feels off (or had been bothering me). BIB has been instrumental in helping me strengthen my back, which had been an issue on and off for years, and improve my overall fitness. Clean and well kept. The trainers, Sean and Taylor, are both extremely personable and knowledgable. Highly recommended.

    Working with the trainers at Built in Boston helped me get back in shape after an injury and several years of being too sedentary. They have customized a fitness program that was perfect for my age and goals and they always give helpful tips about form- I have built my strength back up without any injury- almost a miracle at my age! The trainers are up to date on the latest research in their field and they have fun equipment I haven’t seen anywhere else. It’s always a fun and encouraging environment. I look forward to my training sessions!

    I have been a client at Built In Boston for over 10 years. Sean is a superb trainer- the best of the best! Sean is friendly, encouraging and an amazing coach!

    Built In Boston has the ability to tailor workouts to my needs and fitness level. I have seen improvements in my stamina, muscle tone and overall health. Sean brings a level of encouragement that is so helpful and keeps me motivated. He knows when to push and when to scale back. Workout programs are thoughtfully planned and are effective.

    I will continue to be a client for many more years. I highly recommend Built in Boston!
