Dumbbell Shoulder Fly: Muscles Worked, Benefits, Tips

Dumbbell Shoulder flys, also popular as dumbbell flyes are weight-training exercises performed for increasing upper body strength.

While a dumbbell fly primarily engages your shoulder muscles, it works the muscles in your arms and back as well. Flys can be done using a cable machine, but the simplest equipment used is the dumbbell.

The dumbbell shoulder flys is a good exercise, but you have to do it right, and that usually means picking the right weight.

It is important not to attempt to lift too heavy with this exercise, as that can put you out of shape and put too much stress on the shoulder joint. Always start light, and remember that what felt fine on the first rep can feel very heavy by the fifth.

In fitness, “shoulder exercises” refers to resistance exercises that target the deltoid muscle.

The deltoid is the superficial muscle that forms the rounded contour of your shoulder. While the deltoid is technically a single muscle, anatomically speaking it has three distinct sets of muscles fibers and muscle bellies, which are referred to as deltoid “heads.

The deltoid muscle of the shoulder consists of three separate sections or heads.

What is Shoulder Fly

The shoulder fly or shoulder raise is a fundamental weight training exercise that is great for people who want to build strength or create more definition in the shoulders.

Shoulder flys should be included in upper-body strength training routines, and they should be performed after compounds of exercises that involve the shoulder, such as incline dumbbell press, shoulder press, push-ups, or pull-ups.

There are many different ways to do a fly, such as a front fly, a lateral fly, or a reverse delt fly.

The front fly or front raise primarily strengthens the anterior deltoids, but also works the upper chest (pectorals). It is an isolation exercise for shoulder flexion and can help you build strength and definition in the front of your shoulders.

The side or lateral fly or raise is an effective shoulder-strengthening movement designed to isolate the lateral head of the deltoid muscle

The reverse flys hits the rear deltoid and back parts of your shoulders as effectively as any other exercise, which will contribute greatly to building broader shoulders.

Dumbbell Lateral fly

Dumbbell Shoulder lateral Fly aka Lateral raise is one of the best lateral deltoid exercises to build side deltoids.

To build the middle head of the deltoid muscle, make lateral raises a regular part of your shoulder workout. It’s a must-do exercise.
