Pendulum exercises will help you to perform step-throughs in yoga practice. When you are in tabletop position, on the floor, extend your right leg back. Bend you knee and bring your leg in to your chest. Tuck your head down and attempt to bring your knee to your nose. Then, extend it back again. Flex your foot, when you extend your leg back, and point your toe, when you bring your leg in to your chest. Repeat this ten times, before you switch to the other leg. Now, repeat this exercise, except from downward facing dog position. Repeat this ten times on each side.
