Cambridge Strength & Conditioning

We are a weightlifting club that focuses on fostering a cooperative atmosphere with lots of camaraderie between members.  We have a wide variety of people lifting with us but the common theme between our members is a common goal to be stronger.  We have members who are top ranked weightlifters and powerlifters but also have members who are grandparents lifting for the first time to help maintain muscle and bone density.


We celebrate everyone’s personal achievements whether it’s a state record snatch or someone’s first 135 bench press.  Seeing others push as hard as they can and reach their goals is inspiring and that keeps our members engaged and motivated.


Adaptive Training Studio

Our vision is that people with disabilities are empowered to participate fully in what life has to offer. Our goal is to provide them with the functional training and knowledge to develop their ability to engage in the activities and adventures that they desire.

We exist to bridge the gap between traditional therapy and conventional gyms. We have seen how many people with disabilities leave the protected environment of the medical world without the self-reliance they need to succeed in the real world.
