XFIT-STL head instructor and Xtreme Krav Maga St. Louis owner, Steve Sulze, says that “XFIT training gives students the tools they need to achieve strength and fitness goals they  never imagined to achieve and gives them the confidence and motivation to continue to succeed.

We operate in the extremely high stress environment of a real life attack, and teach students how to function under those conditions. When things go very badly, what we teach ensures they will go home to their families.”

Israeli Self Defense

Krav Maga is the official hand-to-hand combat system of the Israeli Defense Forces. It’s also the preferred system for U.S. Military and law enforcement personnel. Krav Maga is not a traditional martial art. No katas. No rituals. No Non-Sense!

Based on simple principles and instinctive movements, this reality-based system is designed to teach real self defense in the shortest possible time. Learn to defend against common chokes, grabs, and bear hugs, as well as weapons such as guns, knives, and sticks.

Just as important, we teach people to function during the stress and shock of a sudden, violent encounter. Tested on the battlefield and in the streets, Krav Maga’s practical approach to self defense will make you safer and more secure. …more
