Here are a couple of superb videos from the Gracie Academy on escaping the mount. The first video explains the core method escaping from a strangle. The second video shows how to prevent punches and then escape. The videos are very clear and the explanations are excellent.
One thing I would note is that statistically (here in the UK) the most likely way for anyone to be killed is to be stabbed. Once we get past that, there are some differences between men and women. After stabbing, women are statistically most likely to be strangled to death. After stabbing, men are statistically most likely to be kicked and punched to death. These two variations would therefore reflect the male / female difference … although everyone should practise both.
The second thing I noted was the use of “solo preparations” in the instruction. As a karateka, I liked this teaching method as it reflected the “kata – drill – application” process central to the art I’m most familiar with. Put a number of these “solo preparations” end to end and you effectively have a ground fighting kata. This kata – just like normal kata – could be used as a supplementary form of solo practise and a transmittable encapsulation of syllabus.
Anyhow, these are very good instructional videos and well worth as watch.
All the best,
