Rank Requirement: Blue Stripe
Willow Palm is traditionally starts in horse stance with transitions between leaning stances with a horse in-between. Resist the urge to rise up and lock out both knees. Instead, stay at the same height. Bend one knee as the other straightens. Keep the blade of the foot down, kick out the heel. Shoulders are relaxed and eyes are up. Step by Step instructions can be found in “The Art of Shaolin Kempo” by Chris Santillo, Shihan.
I suggest doing the same set from Defensive Posture, while executing proper footwork.
