Dumbbell Incline Alternative Fly

Muscles worked

Setup

1. Set an adjustable bench to a 30-45 degree incline.
2. Sit back on the bench with a dumbbell in each hand, feet planted firmly on the floor for stability.
3. Press both dumbbells directly above your upper chest with a neutral grip (palms facing each other) and a slight bend in the elbows.

How to do it

1. While keeping the left arm locked in the starting position, inhale and slowly lower the right dumbbell in a wide arc until you feel a comfortable stretch in your chest.
2. Exhale and use your chest to pull the right dumbbell back to the starting position, following the same wide arc.
3. Repeat the movement with the left arm while keeping the right arm stationary above your chest.
4. Continue alternating sides with a controlled 2-1-2 tempo (2 seconds down, 1 second pause, 2 seconds up).

Form checklist

• Maintain a slight, fixed bend in the elbows to avoid placing excessive stress on the joint.
• Keep your shoulder blades retracted and pressed firmly into the bench throughout the set.
• Avoid lowering the dumbbell past the plane of your torso to protect the shoulder capsule.
• Keep your core tight and hips glued to the bench to prevent the weight from rotating your body.

Pro tips

• Visualize 'hugging a large tree' to maintain the correct arc and maximize pectoral fiber recruitment.
• Squeeze the stationary dumbbell handle hard to create full-body tension and improve stability for the moving arm.
• Focus on bringing your inner biceps toward your chest at the top of the movement for a peak contraction.

Make it harder

• Add a 3-second isometric hold at the bottom of each rep to increase mechanical tension in the stretched position.
• Perform the movement with a slow 4-second eccentric (lowering) phase to maximize muscle fiber breakdown.
