Setup
- Place a decline bench (set to a 15-30 degree angle) between two cable towers.
- Set the pulleys to the lowest position or slightly above the floor.
- Lie back on the bench, securing your feet firmly under the leg pads.
- Grasp the handles with a neutral grip (palms facing each other) and start with your arms extended out to the sides, level with your lower chest.
How to do it
- Exhale and bring the handles together in a wide arc toward your hips, keeping a slight, fixed bend in your elbows.
- Squeeze your chest muscles hard at the bottom of the movement where the handles meet.
- Inhale and slowly reverse the motion, controlling the weight as you return to the starting position until you feel a deep stretch in your chest.
- Maintain a controlled 2-1-2 tempo (2 seconds down, 1 second squeeze, 2 seconds up).
Form checklist
- Keep your shoulder blades retracted and pinned against the bench throughout the set.
- Maintain a consistent slight bend in the elbows; do not turn the movement into a press.
- Ensure the movement occurs only at the shoulder joint, not the elbows.
- Avoid clanking the weights or handles together at the bottom to maintain tension.
Pro tips
- To maximize the inner chest contraction, slightly cross your wrists over each other at the bottom of the rep.
- Focus on the 'mind-muscle connection' by imagining you are hugging a large tree to keep the arc wide and effective.
Make it harder
- Incorporate a 3-second isometric hold at the peak contraction (bottom of the movement).
- Perform 1.5 reps by going all the way down, halfway up, back down, and then all the way up.
Frequently asked
- What muscles does the cable decline fly work?
- The cable decline fly primarily targets the pectorals, and also works the abs and serratus anterior as secondary muscles.
- What equipment do you need for the cable decline fly?
- The cable decline fly uses cable.
- Is the cable decline fly good for beginners?
- The cable decline fly is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
