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.
