Stuff That Doesn't Really Work!

There are lots of styles that teach connectivity (trapping, locking, sticky hands) to an opponent's limb. There is a lot of stuff out there with a lot of wrist locks of over grabbing punches or knife attacks. A lot of what self defense experts present out there doesn't work like they say it does. It may work on a slow punch or push, but not on fast hard attacks where people half way no how to attack. A lot of what is taught in martial arts are techniques that are supposed to work against someone not trained in what you are doing. So, yeah, maybe some of it will work against your drunk buddy at a party. Most predators are going to do do more than push or hold your wrist. I have never seen a grown man grab another grown man by the wrist  (not even school boys).
