what style is this?

[PalmStriker]

There is a crane technique like that. Hard to say based on your description if that's what you are referring to.

YongChun Southern Crane uses that formation, both in a flying or grounded attack. It is used to disrupt, making way for a power strike. I have only practiced it's use as a grounded attack (frontal) and also as a 360degree one foot grounded spinning disruption before strike. My son, who I used to use as a weight from the time he was a baby until he weighed 60 lbs to practice repetitive one leg outstretched (front) lifts said to me when he was 7 or so that he had been watching me work out for years and showed me one of my techniques I practiced daily. It was the pummeling fists (thread topic) that he chose to demonstrate. https://www.youtube.com/watch?v=P5sb...A6610B&index=9
