Fantastic experience: Joined about a month ago and have been loving it. The community is super welcoming and the coaching is top notch. Lots of class offerings throughout the day, including a very early morning one (5:30!) for those of us who want to exercise before early starts at work. This is the only crossfit gym I've been to but I wouldn't want to go anywhere else.

Fantastic experience: I've been going here for like 7 years! I feel like they really care about having a great community of people who care. During the shutdown, they lent out all their equipment to members, which I really appreciated. I feel like I was coached to scale appropriately but also pushed to improve. Before coming here I never would have thought that I would be able to do pull-ups. I have never been injured doing CrossFit but have been able to do it through multiple injuries (that I got from playing ultimate frisbee smh). Love this place.

Fantastic experience: If you are looking for a fun social distant group fitness class, I highly recommend checking out Crossfit Commonwealth. Commonwealth has done a fantastic job ensuring their athletes feel safe and comfortable while having fun & getting in a great workout! Classes are currently defaulting to outside, and adhere to all MA Covid requirements. Equipment is diligently cleaned between classes, and coaches wear masks in an effort to keep both them & their athletes safe. Programming is written keeping in mind class size (cap is currently 10) to ensure each athlete has their own equipment and doesn't need to share.
