The videos of self-defense training are easily available on the Internet
. Some of them might be totally free of cost but for more professional stuff you might need to pay some money but still the fee of this would be not so much and I think an average person can easily afford to pay for it. You can really benefit by watching these videos as they will show you a variety of useful tactics and tricks that how you can save yourself and apply some techniques against your predator for seeking your self-defense. You can also buy CDs, DVDs, and Cassettes about self-defense training. This is also a good deal but the idea is that you need to practice those techniques at home regularly to master them as early as possible.
