Don't even think about trying the Standing 69 position unless the lifting partner can squat the same weight as that of the other partner.

To get into this position the lifting partner needs a lot of strength and a little bit of patience... The lifter should start from the Sitting 69 position, sitting down in a fairly high chair and help their partner manoeuvre into position, with the lifted partner placing their head between the lifter's legs while wrapping their own legs loosely around the lifter's neck and shoulders, and the arms tightly around the lifter's back.

The lifting partner wraps their own arms tightly around the back of their partner and stands up carefully (keeping their own back as straight as possible), while paying very close attention to their partner's head and neck so as not to knock or strain them.
