Exercise guide

Dumbbell Kneeling Low Fly

  • Intermediate
  • Isolation
  • Rep-based
  • Chest
  • Shoulders

The Dumbbell Kneeling Low Fly is an isolation movement that targets the upper pectorals and anterior deltoids using a low-to-high 'scooping' motion. The kneeling position eliminates leg drive, forcing the core and upper body to stabilize the weight through a large range of motion.

  • Serratus anterior

Equipment

  • Dumbbell

Setup

  1. Kneel on both knees on a soft mat with your torso upright and your core braced.
  2. Hold a dumbbell in each hand at your sides with your palms facing forward (supinated grip).
  3. Maintain a slight, fixed bend in your elbows and keep your chest tall with shoulders retracted.

How to do it

  1. Exhale as you lift the dumbbells forward and upward in a wide arc until they meet at eye level in front of you.
  2. Focus on squeezing your inner chest and bringing your biceps toward each other at the top of the movement.
  3. Inhale as you slowly lower the dumbbells back to the starting position using a controlled 3-second tempo.
  4. Keep the movement fluid and avoid using momentum or swinging the torso.

Form checklist

  • Keep your elbows locked at a consistent slight angle throughout the entire set.
  • Avoid leaning your torso backward as the weights rise; stay perfectly vertical.
  • Keep your shoulders depressed (down) to prevent the traps from taking over the lift.
  • Ensure the palms remain facing upward or slightly inward to maintain tension on the chest.

Pro tips

  • Think about 'scooping' the dumbbells upward rather than just lifting them to better engage the clavicular head of the pectorals.
  • Pause for one second at the peak of the movement to maximize the mind-muscle connection with the upper chest.

Make it harder

  • Perform the exercise unilaterally (one arm at a time) to significantly increase the anti-rotational demand on your core.
  • Slow the eccentric (lowering) phase to 5 seconds to increase time under tension.
