The gym at Delgado Boxing sounds like a percussion section: the impact of gloves on heavy bags keep the pace, and the sounds of shifting feet and jump ropes slapping the floor blend to form a cadence of their own. Featured on CNN as a model small business, Delgado Boxing is the labor of love of pro boxer Paul Delgado, who oversees boxing lessons and boot-camp workouts for adults and kids, that use pugilistic techniques and exercises, keeping the intensity at the high level one would expect from a guy with 20 victories, four knockouts, and only six naps to his name. Though the gym offers premier-level training for those whose ultimate dream is to appear in Madison Square Garden in hooded bathrobes, it welcomes aspiring boxers and fitness seekers of all stripes.
