What is a checkpoint for the Prone Row exercise regarding the forearms on counts 1 and 3?

In the Prone Row exercise, maintaining proper form is crucial for maximizing effectiveness and preventing injury. For counts 1 and 3, the checkpoint specifies that the forearms should be parallel to the ground. This position ensures that the muscles engaged during the exercise—primarily those in the upper back and shoulders—are effectively activated.

By keeping the forearms parallel to the ground, it allows for proper alignment of the body and facilitates the movement of the arms as they row towards the body. This positioning also helps to keep the shoulder blades retracted, which further engages the back muscles. Achieving this alignment not only supports muscle development but also contributes to overall stability and balance during the exercise.

The other options might not provide the correct form required for optimal performance in the Prone Row. For instance, lowering forearms to the ground would disengage the target muscles, while raising them above the head could lead to improper biomechanics and reduce the effectiveness of the movement. Bending at the elbows, while sometimes a part of certain exercises, wouldn't apply to the specific checkpoints of the Prone Row for counts 1 and 3. Therefore, parallel forearms align with the technique needed for this exercise.
