Fast Result Fitness, Irvine

Helmed by Jackie Nguyen—a certified trainer with a 3rd degree black belt in karate and over 20 years of martial-arts training—Fast Result Fitness helps students to achieve their fitness goals with group classes and personal-training sessions. All-levels kickboxing classes focus on both fitness and self-defense as they teach participants how to strike attackers using their fists, elbows, knees, and the occasional cartoon lightning bolt. One-on-one workouts tailored to each individual can build muscle mass, and sport-specific training helps athletes of any experience level to improve their strength and endurance.
