Exercise guide

Kettlebell Low Fly

  • Intermediate
  • Compound
  • Rep-based
  • Chest
  • Shoulders
  • Upper arms

The Kettlebell Low Fly is a standing isolation movement that uses a 'scooping' motion to target the upper pectorals and anterior deltoids. The unique weight distribution of the kettlebell creates a distinct tension curve that emphasizes the peak contraction at the top of the movement.

  • Trapezius

Equipment

  • Kettlebell

Setup

  1. Stand with feet shoulder-width apart, holding a kettlebell in each hand at your sides.
  2. Rotate your palms to face forward (supinated grip) so the bells rest against the back of your forearms.
  3. Maintain a slight bend in the elbows and pull your shoulder blades back and down.

How to do it

  1. Exhale as you lift the kettlebells forward and inward toward the midline of your body in a 'scooping' arc.
  2. Continue the movement until the kettlebells reach chest height, focusing on squeezing the inner chest.
  3. Inhale as you slowly lower the weights back to the starting position using a controlled 3-second eccentric phase.
  4. Keep the bend in your elbows fixed throughout the entire range of motion.

Form checklist

  • Keep your torso stationary; do not lean back or use momentum to swing the weights.
  • Ensure your palms remain facing upward or slightly inward throughout the lift.
  • Maintain a proud chest and avoid letting your shoulders round forward at the top.
  • Stop the movement if you feel excessive strain in the bicep tendons.

Pro tips

  • Focus on driving your elbows toward each other at the top of the rep to maximize pectoral shortening.
  • Think about 'scooping' the weight rather than just lifting it to better engage the upper chest fibers.
  • Maintain a firm grip to stabilize the kettlebell against the forearm, preventing it from flopping.

Make it harder

  • Add a 2-second isometric squeeze at the peak of the contraction.
  • Perform the exercise unilaterally to increase the demand on your core stabilizers.
