Can someone please describe the obliques exercise "Fly Feet"?  Any information is very appreciated.  Thanks.?

Years ago, at a gym, I paid a trainer for 30-60 minute lessons.  Each lesson was on a different muscle.  The lessons rocked.  He wrote down the name of each exercise.

Anyway, I found the list of exercises to improve the OBLIQUES.  I remember most of them.  This was years ago.  Yet, I do not remember the exercise "Fly Feet".

I googled it, youtubed it, and there are so many different answers, I am unsure.

Does anyone know what the exercise "Fly Feet? is?  It works the obliques.  If I remember correctly, it used no equipment.

Please no rude or sarcastic answers.

I've never head of that one, but it may also be known by some other name. The link below has a number of oblique exercises with video snippets of how they are done. Perhaps your 'fly feet' is in there (even if not, there are plenty of good oblique exercises you can do).
