Cable Lying Fly
The cable fly performed in a lying position isolates the chest muscles and maintains constant tension throughout the entire range of motion. It is suitable for developing muscle mass, feel, and stretch without placing a heavy load on the elbow joints. It requires good scapular support and control of the movement.

Why Cable Lying Fly?
The cable bench fly is an effective isolation exercise for the chest muscles, performed in a lying position using a flat bench and cable machine. This exercise offers a unique advantage compared to, for example, dumbbell flies: it maintains constant tension in the chest muscle throughout the entire range of motion. This means that the muscle has to work actively during both the stretching and contraction phases, maximizing the time under tension (TUT) and effectively promoting muscle growth. The movement is excellent for anyone looking to develop chest muscle mass, improve muscle feel, and achieve a deep stretch in the chest muscles without overloading the elbow or shoulder joints. Since the movement does not require the use of heavy weights, it is friendlier to the joints and helps prevent injuries that can arise from heavier compound movements. The cable bench fly is also an ideal option when focusing specifically on isolating and finishing the chest muscles at the end of a chest workout. The effectiveness of the movement is based on the ability to target stress precisely on the chest muscles. However, it requires good scapular support and control of the movement. When performed correctly, the exercise helps develop the shape and definition of the chest muscles, particularly in the inner and lower areas. It is a valuable addition to the chest workout program for both beginners and more experienced fitness enthusiasts, offering versatility and new stimuli for muscle growth.

How to perform
Setup
- Adjust the cable pulleys to the lowest or low position and attach D-handles.
- Place a flat bench between the cable pulleys so that the line of the handles is approximately at shoulder level.
- Grab the handles, sit on the bench, and lower yourself carefully onto your back, keeping your feet firmly on the floor and your buttocks on the bench throughout the movement. Keep your head neutral against the bench, avoiding excessive extension of the neck or lower back. Pull the shoulder blades slightly together and down, lift the chest; lock the elbows at about a 15–30° angle. Bring your hands above your chest with wrists neutral and core tight.
Execution
- Inhale and lower your arms in a wide arc to the sides until you feel a strong but controlled stretch in your chest.
- Keep the elbow angle the same and the shoulder blades tight; do not let the shoulders rotate forward.
- Exhale and squeeze the hands back together above the chest along the same arc, focusing on bringing the upper arms together (not extending the elbows).
Coaching cues
- •Chest up, shoulder blades in your back pockets.
- •Hug a barrel – the elbow angle stays in motion from the shoulder joint; do not push with the elbows or break the elbow angle during the movement so that the stress remains on the chest and does not shift too much to the triceps. Keep the elbows slightly bent throughout the movement, do not lock them fully straight at the top position to avoid excessive load on the elbow joint.
Common mistakes
❌ Too heavy weight
Why it's wrong: Technique suffers, the movement becomes a swing, and the chest muscle does not receive optimal stimulation. Can lead to shoulder pain.
✓ Fix: Choose a weight that allows you to perform the movement in a controlled manner and feel the chest muscle working throughout the entire range of motion.
❌ Straightening or locking the arms
Why it's wrong: Tension shifts from the chest to the elbow and shoulder joints, increasing the risk of injury and reducing chest muscle activation.
✓ Fix: Keep a slight, soft angle in the elbows throughout the movement. The arms should be slightly bent.
❌ Lack of scapular support
Why it's wrong: Shoulders rise to the ears and the chest collapses, which overloads the shoulders and neck, and does not target the stress on the chest.
✓ Fix: Pull the shoulder blades down and together (retraction and depression) and keep the chest elevated and open throughout the movement.
Frequently asked questions
How often should I do the cable bench fly?
You can include it in your chest workout 1-3 times a week depending on your overall training program and recovery. The most important thing is to ensure adequate recovery for the muscle group.
Can the cable bench fly be replaced with dumbbell flies?
Yes, dumbbell flies are a good alternative. However, with cables, you get constant tension throughout the entire range of motion, while with dumbbells, the tension is greatest in the stretching phase and least at the peak of contraction. Both have their own benefits.
What is the correct elbow angle in the movement?
Keep a slight bend in the elbows, about 10-20 degrees, which remains the same throughout the movement. Do not fully straighten your arms or bend them too much to keep the stress on the chest muscles.
Does this exercise help develop the inner part of the chest muscles?
Yes, the cable bench fly is an excellent exercise for targeting stress on the inner part of the chest muscles, especially at the end of the contraction phase when the hands are brought together. It helps create definition between the chest muscles.
Safety tips
- Always start with a light weight and focus on perfect technique before adding weights.
- Ensure stable scapular support and keep the chest elevated throughout the movement to avoid overloading the shoulders.
- Do not allow the elbows to go too deep or hyperextend during the movement.
- Control the movement in both directions; avoid dropping weights or uncontrolled stretching.
- If you feel pain in the shoulders or elbows, check your technique or lighten the weight.
