💠 How to perform the exercise
Preparation
- Choose a pair of dumbbells with an appropriate weight.
- Stand upright with your feet shoulder-width apart.
- Hold the dumbbells by your sides with palms facing inward.
Execution method
- Slowly raise the dumbbells out to the sides until they reach shoulder height.
- Pause briefly at the top and contract the lateral deltoids.
- Lower the dumbbells back down in a controlled manner.
Coaching tips and recommendations
✅ Keep your elbows slightly bent to reduce pressure on the joints.
✅ Avoid swinging your body or using momentum.
✅ Keep your torso stable to prevent unnecessary movement.
✅ Exhale while lifting, inhale while lowering.
✅ Start with light dumbbells and gradually increase the weight.

💠 Muscles engaged in the movement
The dumbbell raise primarily targets the lateral deltoid muscle, but several assisting muscles are also involved in performing the movement correctly.
Main muscles
Synergistic muscles
Stabilizers
Deltoid Muscle
Deltoideus Muscle
🔹 The deltoid muscle is one of the most important and voluminous muscles of the shoulder region. Its primary function is to move the arm in various directions and stabilize the shoulder joint. Due to its triangular shape, it is named “deltoid,” derived from the Greek word “Δέλτα” (delta), meaning triangle.
🔹 The deltoid muscle is divided into three distinct heads, each playing a specific role in shoulder movement. The anterior head assists in forward motions and arm flexion, the middle head is responsible for abduction and lifting the arm, and the posterior head supports extension and movements behind the body. This muscle is essential for the stability and strength of the shoulder joint, and its weakness can lead to limited range of motion, reduced shoulder power, and an increased risk of injury.
✅ Persian Name: Deltoeid
✅ Latin Name: Deltoideus
✅ Common Name: Shoulder Muscle
✅ Location:
🟡 A superficial muscle located at the top of the upper arm, covering the shoulder joint.
🟡 It forms a cap-like structure over the shoulder joint.
🟡 It directly overlays the head of the humerus and originates from the clavicle, scapula, and the upper part of the arm.
✅ 🔹 Origin
✔ Anterior part: from the outer surface of the clavicle
✔ Middle part: from the acromion, a portion of the scapula
✔ Posterior part: from the spine of the scapula
✅ 🔹 Insertion
✔ All parts of the deltoid muscle insert onto the deltoid tuberosity of the humerus.
✅ 🔹 Function
📌 The deltoid muscle is divided into three parts, each with a specific function:
1️⃣ Anterior Head
- ✔ Moving the arm forward (shoulder flexion)
- ✔ Internal rotation of the arm
- ✔ Assists in horizontal adduction of the arm (moving the arm forward across the body)
2️⃣ Middle Head
- ✔ Lifting the arm outward (shoulder abduction)
- ✔ Assists in stabilizing the shoulder during arm elevation
3️⃣ Posterior Head
- ✔ Moving the arm backward (shoulder extension)
- ✔ External rotation of the arm
- ✔ Assists in horizontal abduction of the arm (moving the arm backward across the body)
📌 Function Summary: The deltoid muscle plays a key role in all shoulder movements and is one of the primary muscles responsible for moving the arm in various directions.
✅ 💪🏻 Muscle Fiber Types
✔ The deltoid muscle consists of a combination of fiber types. ✔ A combination of slow-twitch fibers (Type I) and fast-twitch fibers (Type II). ✔ It is composed of both fiber types.
✔ The anterior and posterior heads contain more fast-twitch fibers, which are suited for powerful and rapid movements.
✔ The middle head has a higher proportion of slow-twitch fibers, which help maintain muscular endurance during sustained activity.
✅ 🏋🏻♂️ Role in Sports and Physical Activities
✔ Plays a key role in all overhead movements, such as shoulder press and bench press.
✔ Crucial for sports like weightlifting, swimming, gymnastics, and wrestling.
✔ Considered one of the primary muscles involved in carrying heavy objects, throwing, and raising the arm.

✔ The deltoid plays a vital role in maintaining shoulder joint stability, and its weakness can reduce control over shoulder movements.
✔ This muscle is well-suited for both strength and endurance activities and is heavily engaged in many professional sports.
✅ 🧠 Innervation
✔ Axillary Nerve (also known as the underarm nerve) – responsible for controlling deltoid muscle movements and providing sensation to the shoulder area.
✅ 🩸 Blood Supply
✔ Posterior Circumflex Humeral Artery
✔ Thoracoacromial Artery
✅ 🤼♂️ Role in Sports and Physical Activities
✔ Directly involved in all shoulder and arm movements.
✔ A key muscle for athletes in bodybuilding, weightlifting, swimming, boxing, and combat sports.
✔ Strengthening this muscle improves shoulder shape, prevents injuries, and boosts upper body strength.
✅ 🏌🏻♂️ Interaction with Other Muscles and Joints
✔ Works closely with the rotator cuff muscles, back muscles, and pectoralis major.
✔ Weakness in this muscle can lead to excessive strain on the shoulder and scapular joints, increasing the risk of injury.
✅ 💉 Vulnerability and Potential Issues
✔ One of the most injury-prone muscles in bodybuilding and strength sports due to its crucial role in heavy movements.
✔ Common injuries include tears, strains, tendon inflammation, and cramps—often caused by improper use of heavy weights.
✅ 🏋🏻♂️ Strength Training Exercises for the Deltoid Muscle
1️⃣ Dumbbell or Barbell Shoulder Press – Strengthens all parts of the deltoid
2️⃣ Lateral Raise – Targets the middle head of the deltoid
3️⃣ Bent-Over Reverse Fly – Strengthens the posterior head of the deltoid
4️⃣ Front Raise with Dumbbell or Barbell – Focuses on the anterior head

✔ Wall walks with the hand to improve flexibility
✅ Fun Fact
✔ The deltoid muscle is actually one of the key muscles that shapes and enhances the appearance of the upper body.
✅ Practical Tip
✔ Overtraining the deltoid without strengthening the back and rotator cuff muscles can disrupt shoulder muscle balance.
