Which of the following can increase difficulty by extending the foot off the ground during the pulling phase?

The choice of the alternating prone row as a means to increase difficulty by extending the foot off the ground during the pulling phase is appropriate for several reasons.

In the alternating prone row, as the individual pulls one arm while stabilizing their body in a prone position, the opposite leg can be elevated off the ground. This creates a greater challenge because it requires increased core stability and strength to maintain balance. Elevating a foot during this exercise adds an element of instability that forces the body to engage more muscles, particularly in the core and lower back, to stabilize itself while performing the row.

This dynamic increases the complexity of the movement, putting more emphasis on both the pulling motion of the upper body and the stabilization required from the rest of the body. The combined actions of pulling and balancing on one foot require coordination and enhance overall muscular engagement, making the exercise not only more difficult but also more beneficial for functional strength training.

In contrast, the other options listed, such as asymmetrical Romanian deadlifts, cable lateral lunges, and diagonal medicine ball chops, each involve different mechanics that do not specifically target the pulling phase with the added challenge of foot elevation in the same manner. They vary in focus on leg movement, rotational force, or stability, but
