What is the Rear Delt Fly Machine

The Atlantis Pec / Rear delt fly Machine combo MODEL P156 is a commercial-grade strength training machine that combines two exercise functions in one unit. The machine is designed to help users work out their chest and rear shoulder muscles at the same time.

True Iron Fitness is an authorised distributor of Atlantis Strength. This high-tech machine not only features top-notch biomechanics, but it is also made to last. It is suitable for use in professional gyms and performance training facilities.

Equipped with self-aligning lever arms that rotate on sealed bearings, the machine can follow the user's natural movement path without causing any joint discomfort, thus allowing for smooth, controlled repetitions.

How is this rear delt fly machine different from other standard machines?

Normally, equipment allows only one type of grip, but in the case of this Atlantis Pec / Rear delt fly combo MODEL P156 machine, the user has the option to choose among several handgrip positions to perform both neutral grip chest fly and pronated grip machine rear delt fly exercises.

The overhead cam of the machine allows users to make changes in the range of motion by choosing their preferred starting point. Therefore, the equipment can be used by individuals at different levels of fitness, ranging from beginners to advanced athletes.

Its smart layout not only stimulates harmonious muscle growth but also guarantees a pleasant and effective workout session.

How to do rear delt fly machine exercises on Model P156?

Step by step, you can perform the exercise correctly:

• Release the lever and move the seat up/down until the red line spot on your shoulder/handle meets.

• Drag the grips to a pronated position for rear deltoid isolation.

• Decide the portion of motion you want to perform by cams on top.

• With your chest supported on the pad, extend your arms backward under control.

• Deliberately go back to the start and do the next.

Such a preparation leads to the use of the correct muscles and, at the same time, reduces the risk of overuse of other muscles.

Is the rear delt fly machine effective?

Rear Delt Fly Machine Muscles Worked

The rear delt fly machine muscles worked primarily target the posterior deltoids (rear delts), which play a key role in shoulder stability, posture, and upper-body balance. In addition to the rear delts, this machine effectively engages the rhomboids, middle trapezius, and upper trapezius, supporting controlled shoulder retraction and scapular movement. Secondary muscle involvement includes the teres minor and infraspinatus, which are part of the rotator cuff and help stabilize the shoulder joint during each repetition. By isolating these muscles, the rear delt fly machine allows for safer, more precise training compared to free weights, making it ideal for both beginners and advanced lifters aiming to improve shoulder symmetry, upper-back strength, and injury prevention.
