Your chest just made a new best friend: the chest fly exercise. A cornerstone in any effective chest-building routine, offering a unique way to target your pecs and add definition. 

This exercise is a “must-do” for everyone looking to build strong pecs.

We’ll break down what chest fly is, what muscles it works, and explore 10 exciting variations to keep your workouts fresh.

Getting To Know The Chest Muscles

The chest is made up of two primary muscles: the pectoralis major and the pectoralis minor. 

  • The pectoralis major is the larger, more superficial muscle that gives the chest its broad, defined shape. It’s responsible for movements like pushing, pressing, and bringing your arms together in front of your body. 
  • Beneath it lies the pectoralis minor, a smaller, triangular muscle that plays a crucial role in stabilizing the shoulder blades and assisting with movements like pulling and lifting. 

To work specifically on this muscle, you should look up chest exercises for inner chest.

Together, these muscles work as a team, supporting your upper body’s strength and functionality while contributing to that sculpted, powerful look.

The chest fly targets your pectoralis major, giving your chest that full, Superman look. Additionally, it works the anterior deltoids (shoulders) and biceps as secondary muscles. The movement also engages your stabilizing muscles, such as the core, to maintain balance and control during the exercise.

What Is the Chest Fly Exercise?

The chest fly is a strength-training movement that primarily targets the pectoralis major, the main muscle of your chest. It involves opening and closing your arms in a wide arc, mimicking a “hugging” motion, to stretch and contract the chest muscles

This exercise can be performed using gym machines, dumbbells, resistance bands, or even cables, making it versatile for gym-goers and home fitness enthusiasts alike.

The chest fly can be added to your routine as a primary chest movement or as a finisher. Pair it with pressing exercises like the bench press or chest cable exercises for a comprehensive chest workout. 

Beginners can start with lighter weights, aiming for 3 sets of 12-15 reps, while intermediate lifters may benefit from heavier weights and fewer reps for muscle growth.

This way, you can define how many chest exercises per workout you should do.

Let’s take a closer look at what to watch out for:

  • Overextending your arms can strain the shoulders. 
  • Using too much weight reduces the focus on the chest muscles and compromises form. 
  • Neglecting range of motion limits the effectiveness of the exercise.

Remember: focus on controlled, full movements to get the best results.
