The crucifix lateral raise is a great exercise to target your shoulder muscles, particularly the deltoids. Here's how to do it:
Stand with your feet shoulder-width apart, holding a dumbbell in each hand with your arms extended out to the sides at shoulder height, palms facing down.
Keeping your arms straight, slowly raise the dumbbells to the side until your arms are parallel to the floor, forming a "T" shape with your body.
Hold the position briefly, squeezing your shoulder muscles.
Slowly lower the dumbbells back to the starting position.
