Kickboxing Fitness Training is an iPhone app developed by Khoa Nguyen. It is a free program that offers a high-energy workout that combines martial arts techniques with fast-paced cardio. The app is designed to challenge both beginners and elite athletes alike, by providing a fun and challenging workout that builds stamina, improves self-defense, coordination, flexibility, and burns calories while building lean muscle.

The app is a good fitness choice for anyone looking to burn calories for weight loss or improve stamina and heart health. It is perfect for those who easily get bored with stationary cardio equipment, such as treadmills and stair steppers. The app offers different programs grouped by difficulty levels: Beginner, Intermediate, and Advanced. All kickboxing techniques are designed using 3D modeling with HD videos to provide a better understanding of the moves. The app also tracks calories burned every day and syncs them with Apple Health. Developed by a certified personal trainer, the app requires no gym equipment and can be used anytime, anywhere for men or women.
