Benefit: As a full-round action, make one attack with
an unarmed strike or a special monk weapon, using your
highest base attack bonus but taking a –2 penalty on this
attack roll. If the attack hits, it deals double damage (as does
any other attack you make before the start of your next
turn). If you use this strike to deliver a stunning attack,
increase the save DC to resist the stun by 2. This is an
extraordinary ability.
按照这个描述,你可以在冲锋之前爆腰带对地面乾坤一击,然后冲锋就两倍伤害了……因为说的是any other attack you make ,没有提到target
