Dumbbell flys, also popular as dumbbell flyes are weight-training exercises performed for increasing upper body strength. While a dumbbell fly primarily engages your chest and shoulder muscles, it works the muscles in your arms and back as well. Flys can be done using a cable machine, but the simplest equipment used is the dumbbell.
The different variations of dumbbell flys target the front, middle, and posterior regions of your deltoids. Therefore, these exercises strengthen your shoulders and help improve your ability to lift heavy objects in everyday life.
Performing the dumbbell flys is beneficial to not just the bodybuilders but also for those associated with sports that involve shoulder movements, swinging, and throwing, such as tennis players, swimmers, and footballers.
Since your arms act as levers when performing these exercises, you need to move significantly lesser amount of weight than some of the chest and shoulder presses like the bench press and military press.
