How can I effectively perform a crucifix pushup to target my chest and arms muscles?

To effectively perform a crucifix pushup to target your chest and arms muscles, start in a pushup position with your hands placed wider than shoulder-width apart. Lower your body towards the ground while keeping your elbows out to the sides, resembling a crucifix shape. Push back up to the starting position. Focus on engaging your chest and arm muscles throughout the movement for maximum effectiveness.
