The Seated Hyght Fly is a hybrid isolation movement that targets the lateral deltoids and the clavicular head of the pectorals. By using a specific diagonal path, it maximizes tension on the upper chest and shoulders while minimizing joint strain.

Equipment

  • Dumbbell

Setup

  1. Sit on the edge of a flat bench with your feet firmly planted and a dumbbell in each hand.
  2. Hinge forward slightly at the hips (about 10-15 degrees) while keeping your spine neutral and core engaged.
  3. Let the dumbbells hang at your sides with a neutral grip (palms facing each other) and a slight bend in your elbows.

How to do it

  1. Raise the dumbbells upward and outward at a 45-degree angle from your torso, forming a wide 'V' shape.
  2. Exhale as you lift the weights until they reach approximately eye level, focusing on pushing the weights away from your body.
  3. Inhale as you slowly lower the dumbbells back to the starting position using a controlled 3-second eccentric phase.
  4. Stop the descent just before the dumbbells touch your thighs to maintain constant tension.

Form checklist

  • Keep a slight, fixed bend in the elbows throughout the entire range of motion.
  • Avoid shrugging your shoulders toward your ears; keep your shoulder blades pinned down.
  • Maintain the slight forward lean to ensure the tension stays on the upper chest and side delts.
  • Ensure the movement is strictly at the shoulder joint without swinging the torso.

Pro tips

  • Imagine you are trying to touch the top corners of the room to maximize the reach and lateral tension.
  • Focus on the 'mind-muscle connection' at the top of the rep, squeezing the upper pecs and delts together.
  • Use a lighter weight than you would for standard lateral raises to ensure perfect path mechanics.

Make it harder

  • Incorporate a 2-second isometric pause at the peak of the movement.
  • Perform '1.5 reps' by lifting to the top, lowering halfway, returning to the top, and then lowering fully.
