Gina utilizing her rape prevention tactics from Kuntao Dumpag

Gina Santoro, in the picture above says; as young girls, we are told “not to fight,” but to be "Lady like and gentle." Perhaps one of the disadvantages to our social upbringing is the lack of instinct women need to fight back. In all animal species, the females are the protectors. Except in humans! That is why women are preyed upon; they are seen as the weaker ones.

Let’s change that! Come & learn Self Defense & make it an instinct!

Statistics show, 1 out of every 3 women are victims of assault or rape.

We will show you how not to be that 1 out of 3 at this course!

Don't be one of the statistics! Learn how to protect yourself & your family!


You will learn many counters to the most common attacks women encounter. At the end of the workshop, all women get to beat up a live attacker that will be dressed up in a protective suit. You will be able to see the unique training methods taught at the Practical Self Defense training Center where you will be able to pull off everything you learned within a few hours that day. This seminar is good for both, the inexperienced as well as the experienced martial artist. It does not matter.
