A Lie faceup propping upper body on elbows and forearms. Rest palms facing down by hips. Draw abs in tight. With toes pointed, cross right ankle over left and bend knees and hips about 90 degrees, opening knees out to sides.
B Without moving upper body, lower legs to floor, lightly tapping bottom foot on the ground before lifting legs back up (think of pulling belly button up and in, and try to engage pelvic floor muscles as legs lift). Repeat with opposite ankle crossed on top to complete the set.
