even when getting mugged you might wish to stop an attacker from deploying a weapon or bringing it to bear on your flesh. Bet that will be a "strong grab"...
Where do I collect (and what do I collect)?
My grab was light and sticky instead of "strong". Now I admit that I was VERY fortunate that my assailants very obviously didn't know anything about how to use the knife or mug someone and were clearly relying on me being intimidated. My instinctive reaction created the opposite effect.
For some reason, I have a more difficult time on the mat than I did in that moment. Certainly a part of that is that I have more time to be afraid and that my partners are more skilled.
But that's the point of the training, IMO. Being "strong" that way is exactly what I'm trying to train out of my body.
