Diamondheart Striking & Grappling / Physical Culture Collective is an 8,000 square foot martial arts, strength, and movement studio located on the borders of Bushwick, Bed-Stuy, and Williamsburg in Brooklyn, New York. Established in 2015, the gym offers high-level Muay Thai, Brazilian Jiu-Jitsu (both Gi and No-Gi), Boxing, Wrestling, and Athletic Development programs designed to accommodate everyone from fitness beginners to competitive martial arts practitioners. The gym's philosophy centers on "skill-based play that can be used for sport or self-defense." Led by owner Gavin and a dedicated coaching staff including Hugo, Scott, Jin, Will, Matt, Jesse, Hannah, Brianna, Xtina, and Alex, Diamondheart emphasizes a welcoming, inclusive environment free from toxic masculinity. The coaching team prioritizes gradual course corrections, progressive development at each student's pace, and building sustainable martial arts and movement skills that extend beyond the gym. Diamondheart PCC has built a reputation as a safe, supportive space for all students, particularly women entering martial arts for the first time. The community-focused gym offers programs ranging from Little Diamonds youth classes (ages 6-11) to competition team training, along with specialty classes in kettlebells, yoga, and athletic development. With classes seven days a week from early morning to evening, the gym serves the Brooklyn community with comprehensive martial arts training in a modern, well-equipped facility.
