Impact Bay Area staff are Certified Impact Self-Defense Instructors, who have each completed over 150 training hours in full-force self-defense techniques. Our instructors are versed in physical, verbal and sexual abuse/assault awareness and prevention. We are committed to ending violence by sharing Impact's empowerment and self-defense classes with as many people as possible.
Our full-force courses are team-taught by a "Whistle" Instructor and a "Suited" Instructor. They work together to provide a comprehensive experience for our students.
The Whistle Instructor demonstrates physical and verbal techniques, facilitates group discussions, models how to fight back against a mock assailant, and coaches students during their fights.
The Suited Instructor wears protective gear and plays the role of an assailant, allowing our students to practice techniques from verbal boundary-setting to full-force blows in realistic scenarios.
