"Semi-live" training bridges between drilling and sparring, cooperative training and resistive training, where it can often be difficult to go directly from training on a fully cooperative partner to suddenly training with a fully resistive partner in sparring. After drilling technique against a cooperative partner, before sparring, it is useful to do semi-live training such as positional sparring or with constrained techniques so as to still get more effective practice in those specific areas than could happen during unrestricted sparring, but while guaranteeing there is still a focus in improving in these specific areas.
