If you find the articles on Integrated Protective Concepts interesting and helpful you will enjoy the Staying Safe blog by Christopher Pendas. Christopher takes a proactive approach to personal protection and self defense that provides the reader useful tools and ideas that can be implemented immediately. His approach to developing and enhancing situational awareness goes well beyond the usual prompts to pay attention to your surroundings that are given by so many instructors without really explaining how. In particular he makes a good use of videos to illustrate preincident indicators and other aspects in the context of a real world situation.
The philosophy and approach outlined on the Staying Safe blog complements our approach at Integrated Protective Concepts and is highly recommended.
