Put the handle on the pylon. Get into lean position and think of a tug of war. If you are trying to pull with the most force and power it is an arms straight position. Extend handle and relax the arms like @bishop8950 was saying and feel the force on your hands increase.
Conversely, bend your arms as if pulling with them, not moving your feet and see what happens. Body comes up and force decreases equaling a less powerful position.
