Rumble Boxing Greater Boston on Instagram: "Our Rumble team was in full effect at HYROX Boston @hyroxamerica 🥊💪 Coach Kev and Coach Jen stepped up to the challenge, and right behind them was the entire Rumble community. One thing we always stand by—and our biggest focus coming into the month of October—is this: No one fights alone. So get ready to bring a new friend every day for the month of October. Congratulations to Coach Kev and Coach Jen on conquering the World Series of Fitness — HYROX!
