I would agree with the grappling/BJJ to a point. However, stand-up skills should not be overlooked for a self-defense curriculum. Often simple striking can be taught, and drilled, effectively.
I would recommend the following styles/drills:
- Boxing (for strikes/clinch)
- "Straight Blast" (repeated strikes w/ the ball of the hand to the nose/forehead/face of the attacker)
- This causes disorientation in an attacker and can be employed effectively due to the fact that it requires little accuracy.
- Judo (for throws/locks)
I would have to caution against grappling due to the fact that a smaller woman against a larger attacker may be in greater danger on the ground then on her feet. I would suggest most grappling be focused on escapes not submissions.
