Chest fly exercise
The Chest fly exercise is one where you lie on your back and knees with your feet flat on the floor. You will need dumbbells for this exercise. Hold dumbbells with your arms extended directly above your shoulders, with your palms facing one another. Using your chest and shoulder muscles, inhale while slowly opening the arms wide towards the ground. While you exhale, use chest and shoulder muscles to push the arms and dumbbells back up to the beginning position. I would suggest doing this movement for 10 repetitions the first time. In future sessions, increase time and the number of reps.
