Ducking Osis is a duck followed by an Osis.
Demonstration of a Ducking Osis.
Set the footbag high enough to give yourself time to duck underneath it and prepare for the Osis.
Lower your head and move underneath the footbag as it rises, then quickly spot it as it begins to fall behind you.
Stay balanced as you pivot away from the footbag and bring your stalling foot underneath it for a clean clipper catch.
