These self defence classes were an excellent introduction to the skills needed to feel confident about being attacked on the street & in one’s own home. We were taught that the adrenalin of fear is really adrenaline to confront an aggressor. As a woman I am not a mere “weakling” but someone who is ready to defend myself using the skills taught in these classes. John is an excellent teacher with the knowledge to inform about the most effective strategies to tackle an aggressor in any situation. I would recommend these classes to anyone who feels the need to learn how to protect oneself in any confrontational situation.
