Boston Underground Strength Training is a private strength training facility born out of Waltham, MA just about 9 years ago.
In the beginning...
We originally started training at a playground behind a local restaurant. There was nothing fancy about what we had for equipment, as most of it was homemade. Every Thursday we would load up a friend’s truck and head to the nearby playground, unload the equipment and wait for the kids to come and train. We would train anyone that wanted to train. Rain or Shine. Looking around at the end of every session, we knew we could build this into something bigger and also be able to offer it to anyone willing and wanting to train and learn. Having worked in private, commercial, and sports performance settings, we felt as though we could blend the experiences we’ve had in those settings and provide a unique and high-quality experience for the people. An experience that would provide an atmosphere where people take ownership of what they are doing and learning.
What we're about.
We believe that what you do inside our facility should transfer to what you do outside of our facility.
We offer a simple, no-nonsense approach to training in a high-energy environment, focusing on both small and large group training. We keep it simple - our facility is equipped with the essentials and our highly-motivated coaches are here to ensure you make progress each step of the way.
Our priority is you, and our goal is to help you reach your full potential. We pride ourselves on offering you an environment in which you feel comfortable, but most importantly, an environment when you can truly focus on building around your lifestyle, not just an image.
I can't recommend this place enough. For the first time in my life I enjoy going to the gym. It changed my life. ~ Hayley H.
I couldn't have asked for a better place! Even while struggling to get out of bed after day 1, I found myself anxious and excited for our next workout. ~ Adam C.
