TECHNIQUE STARTING POSITION Begin position seated on the ground with the upper back against a padded bench for support just below the scapula. This point of contact should not change throughout the duration of the movement. The arms may either span the width of the bench for added stability or folded across the chest, depending on personal preference. Next, shift the feet toward the glutes and drive the heels into the ground. While pushing through the heels of the feet, extend the hips so that the torso and thighs form a straight line from the shoulders to the knees, paral- lel to the ground (Figure 1A). Knees should be flexed so that the shins are perpendicular to the ground, and the shin and thigh form a 908 angle at the knee. Adjust feet as necessary to attain this positioning. The spine and the hips should remain Figure 2.

Once a stable position has been achieved, lightly shift the weight into the right heel without adducting the right thigh.
