Principles of improv
Preparation for improv consists of warmup exercises intended to create the appropriate mindset. We want to shed any stress or anxiety from the day, stretch our bodies to help relax, and warmup our minds and intuition to foster the free-flowing spontaneity and stream of consciousness essential for improv.
Accept your partner’s “offer” or claim, i.e., never deny or invalidate their statements. E.g., if your partner says, “Why are you so anxious?”, you must not deny their offer but instead accept it as true, i.e., accept and agree that you are anxious. This is essentially the YES part of the traditional YES, AND.
