Dumbbell Decline One Arm Fly

Dumbbell Decline One Arm Fly

The Dumbbell Decline One Arm Fly is a fantastic exercise that targets the chest muscles, specifically the lower and outer portions. It is an ideal exercise for individuals looking to add definition and shape to their chest, creating a more sculpted appearance. This exercise is typically performed on a decline bench, which adds an additional challenge by increasing the range of motion and activating the lower chest fibers. Using dumbbells allows for unilateral training, meaning you work each side of your chest independently. This helps to correct any imbalances between the left and right sides of your body. By isolating one arm at a time, you also engage your core to stabilize your body throughout the movement, providing an added bonus of core activation and development. The decline angle of the bench helps to shift the emphasis from the upper chest to the lower chest, making it an excellent exercise for overall chest development. It also targets the pectoralis major and pectoralis minor muscles, along with the anterior deltoids and triceps. When executing the Dumbbell Decline One Arm Fly with proper form and control, you can effectively engage the target muscles, leading to enhanced muscular strength and definition in your chest. So, if you're looking to add variety to your chest workout routine, this exercise is a must-try. Remember to start with a weight that you can handle comfortably and gradually increase it as your strength improves.


  • Lie face up on a decline bench with a dumbbell in one hand and your arm fully extended above your chest. The other hand can be placed on your hip.
  • Lower the dumbbell in a wide arc while keeping your arm slightly bent. The dumbbell should be parallel to the floor at the bottom position.
  • Slowly raise the dumbbell back up to the starting position, making sure to maintain control throughout the movement.
  • Repeat for the desired number of repetitions, then switch arms and repeat the exercise.

Tips & Tricks

  • Maintain proper form and technique throughout the exercise.
  • Engage your core muscles to stabilize your body during the movement.
  • Focus on squeezing your chest muscles as you bring the dumbbell back up.
