Cable One Arm Decline Chest Fly

Muscles worked

Setup

1. Position a decline bench at a 15-30 degree angle next to a cable tower.
2. Set the pulley height so it is level with your chest when lying on the bench.
3. Lie on the bench, secure your feet, and grasp the handle with the arm closest to the pulley using a neutral grip.
4. Start with your arm extended out to the side, maintaining a slight bend in the elbow and your shoulder blade pinned against the bench.

How to do it

1. Exhale as you pull the handle across your body toward the midline in a wide arc, following the angle of the decline.
2. Squeeze your lower chest at the peak of the movement, bringing your hand slightly past the center of your torso for a deeper contraction.
3. Inhale as you slowly return the weight to the starting position, maintaining the slight bend in your elbow throughout the eccentric phase.
4. Perform all reps on one side before switching to the other, maintaining a controlled 2-1-2 tempo.

Form checklist

• Keep your shoulder blades retracted and depressed into the bench throughout the set.
• Maintain a fixed, slight bend in the elbow to keep the tension on the pectorals rather than the joint.
• Avoid rotating your torso toward the cable; keep your hips and shoulders square to the ceiling.
• Ensure the movement occurs only at the shoulder joint, not the elbow.

Pro tips

• Focus on bringing your inner bicep toward your sternum to achieve maximum shortening of the pectoral fibers.
• Place your non-working hand on the working pectoral muscle to enhance the mind-muscle connection and feel the contraction.
• At the peak of the movement, imagine you are trying to reach your hand toward your opposite hip to better align with the lower pec fibers.

Make it harder

• Add a 2-second isometric hold at the point of maximum contraction (across the midline).
• Slow down the eccentric (lowering) phase to 4 seconds to increase time under tension.
