For many people, a huge part of their lives in their neighborhoods is where they work out. Many people in Boston might not know this, but the North End has a very vibrant and robust fitness community. I sat down with Melina DiPaola, owner of the gym cult favorite Ride North End, and her newest venture - a boxing studio - Knockout North End. We discussed all things health, fitness, and growing up in the North End, one of Boston's oldest and most historic neighborhoods.
