How To Do A Chest Fly
What is a chest fly?
See all chest fly exercise variations
The chest fly is an isolation exercise which targets the pectoralis major, pectoralis minor, deltoids, triceps, and biceps, although the focus is mainly on the pectorals. In addition to building chest muscle, the chest fly helps to open up the chest and shoulders which can reduce tightness, increase range of motion, and combat poor posture.
Where the bench press is great for building strength and power, chest flyes are really suited to building size, so if your goal is a bigger chest, add them into your routine. Different variations work the muscles in a slightly different way, so you may want to add a few variations. As an isolation exercise, this is best suited as a finisher.
COMMONLY ASKED QUESTIONS ABOUT CHEST FLYES
To build chest mass, you need to break down the chest muscles through training. The process of repairing these tears leads to bigger, stronger muscles.
Most people turn to the bench press when they want to pack on muscle, but chest flyes are great for building mass when used correctly - form here is key.
If you're serious about building your chest, you'll need to train your chest at least twice a week and include a mix of compound and isolation exercises. You'll also need to get enough protein, and consider going on a bulk.
It is possible to do chest flyes on the floor, but you will get a deeper range of motion performing this exercise on a bench.
Long story short - if you have access to the bench, use one. If not, the floor will be fine!
Cable flyes are slightly more effective as they provide resistance throughout the entire movement, whereas dumbbells do not produce significant tension at the top portion.
That said, both the cable chest fly and dumbbell fly are still extremely effective at working your chest, so if you prefer one over the other (or any of the other chest fly variations we cover below), go for whichever one feels best.
Chest fly exercise tips
- Start with a low weight and really focus on controlling the movement and building your mind-muscle connection. Poor form can cause serious injury.
- Keep within a safe range of motion. Aim to get your arms just below parallel with the ground, but if you feel a stretch in your chest before, stop then.
- Squeeze your shoulder blades together throughout the movement. This protects your shoulders and puts the focus on the chest.
