Final answer:
Proper push up technique requires maintaining body alignment, shoulder width arm position, and keeping the head down.
Step-by-step explanation:
The most important factor for a proper push up is body alignment. It is crucial to maintain a straight line from your head to your toes. This ensures that you are engaging the correct muscles and maximizing the effectiveness of the exercise. In addition, keeping your arms shoulder width apart helps to maintain proper form and target the desired muscle groups. Lastly, keeping your head down helps to maintain a neutral spine alignment and prevents straining your neck.
