Dumbbell One Arm Bench Fly

Dumbbell One Arm Bench Fly

The Dumbbell One Arm Bench Fly is an effective exercise that targets and strengthens your chest muscles, specifically the pectoralis major and minor. This exercise primarily focuses on the upper chest region, helping to sculpt and tone your chest for a more defined and chiseled appearance. To perform this exercise, you will need a flat bench and a pair of dumbbells. Lie face up on the bench with one dumbbell in your hand, perpendicular to your body. With your arm slightly bent at the elbow, slowly lower the dumbbell out to the side in a wide arc while maintaining control. Pause for a brief moment when your arm is parallel to the ground, and then return the weight back up to the starting position. Repeat the same movement with the other arm. The Dumbbell One Arm Bench Fly is a versatile exercise that can be done in the comfort of your own home or at the gym. It not only helps to develop strength and size in your chest muscles, but it also engages other stabilizing muscles in your shoulders and arms. Remember to use slow and controlled movements throughout the exercise to maximize muscle engagement and minimize the risk of injury. Integrating the Dumbbell One Arm Bench Fly into your workout routine can help you achieve a well-rounded and balanced upper body physique. Aim for 2-3 sets of 10-15 repetitions on each arm, gradually increasing the weight as your strength improves. As with any exercise, it's important to maintain proper form and listen to your body. Are you ready to take your chest training to the next level? Give the Dumbbell One Arm Bench Fly a try and watch your chest muscles soar to new heights!


  • Start by positioning a bench horizontally and grabbing a dumbbell in one hand.
  • Sit down on the bench with your feet flat on the ground.
  • Lean forward and place the dumbbell on the same side of the bench as your working arm.
  • With a neutral grip, lift the dumbbell in front of you, extending your arm while keeping a slight bend in your elbow.
  • Slowly lower the dumbbell out to your side, keeping your elbow slightly bent and your arm parallel to the floor.
  • Pause for a moment at the bottom of the movement, feeling the stretch in your chest muscles.
  • Engage your chest muscles to bring the dumbbell back to the starting position, keeping your arm parallel to the floor.
  • Repeat for the desired number of repetitions and then switch to the other arm.
