The right way to do it: - Legs in tabletop position, knees stacked above the hips, in a 90-degree angle. - Pelvis in imprint. - Contract your belly to pull your navel to your spine. - Slowly lower your right foot and leg to “tap” the floor. Keep the 90-degree bend in the knee as you lower. . What not to do: - Avoid bending the knee past 90 degrees
