Performing the: A Step-by-Step Tutorial Dumbbell Fly on Exercise Ball
With your hips lifted and your body forming a straight line from knees to shoulders, hold the dumbbells directly above your chest with your palms facing each other and elbows slightly bent.
Slowly lower the weights in an arc out to the sides of your body, keeping the slight bend in your elbows, until your arms are parallel to the floor.
Pause for a moment at the bottom of the movement, then use your chest muscles to raise the weights back to the starting position in the same wide arc.
Repeat the movement for the desired number of repetitions, ensuring to keep your hips lifted and your body stable throughout the exercise.
