We practice pre-emptive striking as a matter of course, but how can we train for the mental and emotional aspects of actually hitting another person, as opposed to a focus mitt? What drills and conditioning can prepare us to 'pull the trigger' when we need to? Obviously being able to hit hard is fundamental to self-protection, but overcoming our natural reluctance to hit another is equally key, I think. After all if we hit first we're seen as being a bully. If we don't we're likely to get hurt and perhaps not be able to recover sufficiently and in time to perseverve.
Does anyone have any suggestions as to how to develop the ability to switch on at need (and, equally importantly, to switch off again just as quickly)?
