Community Highlight:
The Phoenix is built on one idea: recovery is stronger in community.
Since 2006, they’ve reached nearly a million people impacted by substance use and mental health challenges — and CrossFit has become their most popular program. More than 100,000 people have found sobriety and support through Phoenix CrossFit classes, with 83% staying sober beyond the three-month mark.

We spoke with Gavin Young, a Phoenix leader and longtime CrossFit athlete in recovery, who shared how daily progress in training — one more rep, one more pound, one more second — becomes a cornerstone in rebuilding lives.
From Boston to Denver to Philadelphia, The Phoenix is proving what’s possible when fitness meets recovery: a resilient community built on hope, accountability, and shared struggle — one workout at a time.
