Which body position must be maintained during the hand release pushup for it to be valid?

The requirement for maintaining a flat body position on the ground during the hand release pushup is crucial for ensuring that the exercise is valid. This position ensures that the core, chest, hips, and legs are all aligned and in contact with the ground at the start and end of the repetition. A flat body position also guarantees proper form, activating the intended muscle groups effectively, including the chest, shoulders, and triceps.

In contrast, having arms bent would prevent the full range of motion necessary for a pushup, as the correct form involves extending the arms fully to the ground before releasing the hands. An elevated body position would negate the mechanics of a standard pushup, making it easier than intended and compromising the intended fitness goals of the exercise. Keeping the head down is not a specific requirement for the hand release pushup; instead, it’s more about ensuring the body forms a straight line from head to heels, maintaining proper alignment for both safety and effectiveness.
