How Does it Work?

Whether you’re seeking to build upper body strength or improve core stability, understanding the mechanics of a well-executed dumbbell fly is key. Stay tuned as we unravel the effectiveness of this great exercise with the use of dumbbells for building chest muscles and pectoral strength.

The Importance of Dumbbell Flys in Strength Training, Bodybuilding, and Overall Wellness

Don’t overlook the dumbbell chest fly. This exercise is a powerhouse for developing your pecs and other arm-assisting muscles. Whether you’re an athlete or just want to improve your overall wellness, incorporating dumbbell flys into your routine can yield significant gains.

#1 Targeted Muscles

Dumbbell flys target your chest, shoulder, and upper arm muscles.  Especially the pectoralis major muscles.  These are commonly known as pecs, or chest muscles. Developed pectoral muscles give your chest a well-defined and stronger look. 

This exercise adds a unique twist of flexion and adduction to stimulate those muscles in a whole new way.  Combine flyes with push-ups and bench presses to give your body a well-rounded chest workout. Your core is activated as your body requires stabilization. Therefore, a side effect of this workout is improved core strength.

This exercise also activates the anterior deltoid muscles (the front of your shoulder muscles) and biceps brachii (your upper arm muscles). Your shoulders, chest, arms, and core are all working together as you do the dumbbell fly. 

#2 Good Posture

Not only do dumbbell flies build impressive pecs, but they also improve your posture. Strengthening your shoulder girdle helps keep your shoulders back and prevents that dreaded forward rounding. Say goodbye to slouching and hello to a pain-free back and injury prevention.

Incorporating dumbbell flies into your fitness regime is more than just about looking good; it’s about enhancing functional strength and maintaining good health too. Next time you hit the gym, don’t neglect to include a few sets of dumbbell flyes – your body will be thankful for it.  

Step-by-step Instructions to Perform a Dumbbell Fly

The dumbbell fly is a great exercise to build upper body strength, especially in the chest muscles. Here’s how to do it right:

Preparing for the Exercise

Grab a pair of dumbbells that challenge you, but start with a manageable weight.  If this is your first attempt, start with 5 to 15-pound weights and focus on your form. Lie down on a flat bench with your feet planted firmly. Hold the weights close to your chest with palms facing each other.  For proper form have your upper back flat on the bench.  Your back muscles will not be activated, so they should remain neutral.  

Performing this exercise on a Bosu ball will require more focus on stability and will add intensity.  Bosu balls are half of an inflated exercise ball that provides an unstable surface and therefore provides more input to your overall core strength.

Executing Proper Form- How to Do the Dumbbell Fly

#1 Set Up and Form

The Dumbbell fly is a single-joint movement, therefore starting with light weight is important.   Do not hinge at the elbow, but do not keep your elbows locked out either.  Keep your elbow fixed with a slight bend throughout the movement. (an approximately 10-degree bend) Keep your elbow turned up all the way through the movement. Do not rotate the arms, as you may experience stress in the elbow. 

#2 Points of Contact

Pick up your dumbbells, and sit on the bench.  You will want to have your feet planted on the ground underneath your knees and have your dumbbells resting on your knees.  When you start leaning back, use your knees to hoist the dumbbells above your head as you will put your back, and head flat on the bench.  

#3 The Movement

Keep your elbows fixed at a slight bend and open up your chest as you move the dumbbells.  Keep the movement slow and controlled.

#4 Depth

Lower the dumbbells until you feel a good stretch.  Do not extend past that feeling, as you may start feeling a strain on your joints.  Lower the dumbbells as far as you can before deviating from your form.

#5 Repeat

  • Lift: Push those dumbbells up toward the ceiling, using your elbows, not your wrists.
  • Squeeze: Squeeze your pecs together like you’re trying to hold a sandwich between them. Keep those weights close. Feel the burn in your chest, back, and shoulder blades.
  • Fly: Slowly lower the weights outwards, keeping a slight bend in your elbows. Don’t let those dumbbells fly away.
  • Pull Back: Contract your pecs and pull the dumbbells back up, completing one rep of the dumbbell chest fly exercise.

Incorporate different dumbbell fly variations, like incline or decline flies, to level up your upper body strength and get those pecs poppin’. And remember, keep your shoulders back and engaged throughout the exercise to avoid any shoulder strain and maintain good posture. Complementary exercises to add would be the bench press or upper back exercises. Respect everyone’s space and put your dumbbells back when you’re done.

Increasing Shoulder Strength vs. Enhancing Definition

The dumbbell fly exercise can be incorporated into strength training and bodybuilding routines.  If your goal is to increase strength, include high intensity in the weight of the dumbbell combined with a small number of reps and full rest between sets.  If you want to build a chest, increase the volume of reps and sets.

Increasing Strength 

The key to increasing strength with the dumbbell fly would be to to 1-5 reps at 80%-100% of your max effort. You can do multiple sets, but make sure you have plenty of rest.

Body Building
