Beginning (my grandma on the left) – Use a pillow or ball on the ground, start on one side of the pillow then step over to the other side.
Intermediate (my mom in the middle) – Use a pillow or ball on the ground, place one knee up with foot hovering over the pillow, then hop to the other side lifting your other knee.
Advanced (me on the left) – Using a pillow or ball on the ground, hop side to side with both feet, keep repeating.
