Description

A dumbbell exercise that targets the chest muscles by performing a flying motion with one arm while lying on the floor.

How to Do Dumbbell One Arm Floor Fly

  1. 1
    Setup

    Lie on your back on the floor with your knees bent and feet flat. Hold one dumbbell in one hand with a neutral grip (palm facing your feet), extending your arm straight up towards the ceiling with a slight elbow bend.

  2. 2
    Setup

    Place your free hand on your stomach or out to the side for stability. Ensure the shoulder blade on your working side remains pressed into the floor.

  3. 3

    Inhale and slowly lower the dumbbell in a wide arc motion out to the side until your upper arm gently touches the floor. Maintain the slight bend in your elbow throughout this movement.

  4. 4

    Exhale and contract your chest to reverse the motion, bringing the dumbbell back up in the same arc path until it's directly over your chest. Focus on squeezing your pectoral muscle at the top.

  5. 5

    Repeat for the desired number of repetitions on one side, then switch arms and perform the exercise with the other arm.

Tips

  • Control the descent: Don't let gravity simply drop the weight; control the eccentric phase to maximize muscle engagement and prevent injury.
  • Maintain a slight elbow bend: Keep a consistent, slight bend in your elbow throughout the entire movement to protect your elbow joint and keep tension on the chest, not the biceps.
  • Focus on the squeeze: At the top of the movement, actively squeeze your chest muscle as if trying to bring your bicep to your sternum, enhancing peak contraction.
  • Utilize the floor as a safety stop: The floor provides a natural, consistent stopping point, preventing overstretching and ensuring a safe range of motion.

Common Mistakes

  • ×Using too much weight leading to elbow lockout: Reduce the dumbbell weight to maintain a slight elbow bend and controlled, fluid movement, rather than locking out your elbow and swinging the weight.
  • ×Arching the lower back: Keep your core engaged and your lower back pressed into the ground for stability and spinal protection, instead of arching your lower back off the floor.
  • ×Rushing the movement: Slow down the eccentric (lowering) phase to maximize time under tension and improve muscle activation, rather than rushing through the movement.
