Meet Coach Sammy! 👋

Sammy has been part of both the CrossFit Accolade and Commonwealth CrossFit communities, and now we’re excited to welcome her to the coaching team at both gyms!

She started CrossFit in 2016 and has been hooked ever since. Sammy loves the challenge of learning new skills, encouraging others along the way, and most of all the friendships and community that come with CrossFit. She also brings coaching experience from RowHouse in Denver and is always up for a workout involving a barbell or rowing machine!

Outside the gym, Sammy works in fundraising for a Boston-based nonprofit and enjoys snowboarding, hiking, live music, and walks with her dog, Jackson. She also spent two years living in Eswatini as a Peace Corps Volunteer!

We’re so excited to have Sammy on the team. Give her a warm welcome when you see her in class! 💙

Murph is never just a workout.
It’s a chance to remember, honor, and come together as a community. Grateful for everyone who showed up today, pushed through, supported one another, and honored the true meaning of Memorial Day.

Every Memorial Day we take on The Murph to honor Lt. Michael P. Murphy and all those who’ve made the ultimate sacrifice. A powerful tradition and a great way to track your progress year-over-year with CrossFit.

The Murph is challenging but when scaled is accessible to all. Common scaling includes cutting the reps in half or substituting movements like ring rows for pull ups. Coach Mike will help members select the appropriate scaling that day.

📆Join us on Memorial Day, Monday May, 25, at 8:45 or 10:00
📍Commonwealth CrossFit 630 Somerville Ave., Somerville, MA 02143

It just might be one of the most rewarding workouts you’ll complete all year.

Let’s hear it for Coach Larry and Coach Danny from and Zack from for trying something new and competing in a strongman competition today! And for placing 2nd and 3rd!

Proud of these guys for stepping outside their comfort zone and testing their strength in a new arena, proving that real growth happens when you’re willing to try something new.
