About
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 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.

Coach
After graduating from James Madison University with a degree in Communications, Angela moved back to Boston and began her work at a health club. She has since been in the industry for almost ten years, a majority of the time spent in the administration and operations end. When it came to her own fitness, she started working with a personal trainer who introduced her to strength training. Working with trainers gave her a better understanding of the value that came with that coaching and the importance of being taught how to properly strength train. She absorbed everything taught to her and wanted to further explore training and teaching.
Angela began her fitness career teaching group exercise classes. With certifications in both Pilates Mat and Barre, she has taught all different ages, abilities, and body types, most of the time within the same class. The opportunity to teach in a large group training setting has given Angela the understanding that not all bodies are alike and adjustments for styles of learning and abilities do need to be made to ensure the success of an individual - all valuable lessons that she applies to her coaching at Boston Underground Strength Training.
Wanting to become more involved on the personal training side of fitness, Angela became a Certified Personal Trainer through the National Academy of Sports Medicine. Being in a health club offered her the opportunity to continue her work in the fitness industry with a variety of clients with different goals and needs. Seeing that there was a need to further educate herself and her clients in strength training, she decided to further expand her education by becoming a Certified Functional Strength Coach.
Angela first began at Underground as a member, in both semi privates and strength camps. She immediately fell in love with the gym’s mission and culture. The way in which Boston Underground approached training resonated very strongly with Angela and she saw an even greater opportunity to grow as a coach. Now part of the team, she utilizes her unique background in group fitness and strength training to tailor her coaching to each individual ‘s learning style and abilities.
