Dumbbell One Arm Floor Fly

The Dumbbell One Arm Floor Fly targets the chest muscles while providing stability and control.

  1. Lie on your back on the floor with a dumbbell in one hand.
  2. Extend your arm straight above your chest.
  3. Lower the dumbbell out to the side in a controlled manner, keeping a slight bend in your elbow.
  4. Bring the dumbbell back to the starting position, squeezing your chest at the top.

How to perform the Dumbbell One Arm Floor Fly

  1. Set up. Set up in a stable, balanced starting position appropriate for the Dumbbell One Arm Floor Fly using your dumbbell.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your biceps.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your biceps rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
