Beginner`s Tip:Instead of simply resting your hands on your knees in the standing position, firmly press the bases of your palms against the very tops of the thighs (right hand on the right thigh, left hand on the left). This downward pressure on the femur bones will create a slight natural hollowing of your lower belly.

For those finding difficulty, this asana can also be performed sitting in the Padmasana as well.
