Fury Combat, Brooklyn

After earning a 10th-degree black belt and retiring from life as a United States Secret Service operative, Grandmaster Dr. David Fury set out to create his own brand of fighting style. Informed by his professional background and competitive-fighting experience, the Fury system teaches close quarters, hand-to-hand combat and tactics. Students learn hard and fast striking moves intended to defuse a single or multiple attackers, as well as weapons-based fighting skills. Held seven days a week, classes can help students transform common household items into weapon—including an old magazine, kitchen utensils, or your coupon book for free hugs.
