💠 Exercise guide
The Medicine Ball Overhead Throw is an excellent explosive exercise for developing upper body power and enhancing force transfer from top to bottom. Widely used in athletic programs—especially in CrossFit and combat training—it simultaneously engages the shoulders, chest, and core muscles, helping to improve overall physical performance.
💠 How to perform the exercise
Preparation
✅ Stand tall and hold the medicine ball overhead with both hands
✅ Feet hip-width apart, knees slightly bent
✅ Core engaged, eyes forward, elbows close to the ears
Execution method
✅ Forcefully throw the ball down toward the ground or forward in one powerful motion
✅ At the moment of release, engage the shoulders, chest, and core muscles
✅ Allow the entire body to contribute to the transfer of force, then pick up the ball and repeat
Coaching tips and recommendations
✔ Keep the elbows from flaring out too much to reduce shoulder strain
✔ Exhale during the throw to enhance core performance
✔ Use a non-bouncing (dead) ball for greater safety
✔ Keep the torso and back straight and strong; avoid excessive forward bending
Benefits of the exercise
🔹 Shoulder strengthening with an explosive movement:
The anterior deltoid plays the primary role in the throwing motion, and this exercise enhances shoulder throwing performance in combat and team sports.
🔹 Functional engagement of the chest and triceps:
Alongside the shoulders, the chest and triceps are activated during the throw, enhancing the performance of the pressing muscles.
🔹 Increased core strength:
Engaging the abdominals and torso, especially during force transfer, improves midsection control and helps prevent lower back injuries.
🔹 Application in fat-burning and HIIT workouts:
The explosive nature of the movement and the involvement of multiple muscle groups make this exercise an excellent option for increasing workout intensity.
💠 Muscles engaged in the movement
In this exercise, the explosive overhead throwing motion engages multiple muscle groups simultaneously. The anterior deltoid acts as the primary mover, the chest and triceps provide support, and the core muscles stabilize the midsection. This combination enables efficient force transfer and improves overall body power.

Synergistic muscles
Stabilizers
Anterior Deltoid muscle
Anterior Deltoid Muscle
🔹 The anterior deltoid is one of the three parts of the deltoid muscle. Its primary functions are moving the arm forward (flexion), internal rotation, and assisting in horizontal shoulder movements. This muscle plays a key role in many upper-body exercises, especially strength training movements like bench press, front raises, and throwing actions.
🔹 The anterior deltoid is one of the most important muscles involved in pressing and pushing movements. Due to its engagement in many strength exercises, it is often well-developed among athletes and bodybuilders. However, overusing this muscle without strengthening the posterior shoulder muscles (posterior deltoid and rotator cuff) can lead to muscular imbalances and increase the risk of shoulder injuries.
✅ Persian Name: Deltoid Ghodami
✅ Latin Name: Anterior Deltoid
✅ Common Names: Front part of the deltoid muscle | Anterior head of the shoulder
✅ Location:
🟡 Located at the front of the shoulder, forming the anterior part of the deltoid muscle.
🟡 Originates from the clavicle and lies over the upper part of the humerus.
🟡 Alongside the middle and posterior parts of the deltoid, it acts as part of the shoulder cap and assists in arm movements.
✅ 🔹 Origin
✔ Anterior surface of the lateral third of the clavicle (Clavicle – Anterior Surface of Lateral Third)
✅ 🔹 Insertion
✔ Deltoid tuberosity on the humerus bone (Deltoid Tuberosity, Humerus)
✅ 🔹 Function
📌 Primary functions of the anterior deltoid:
✔ Arm flexion – moving the arm forward (like raising the hand in front of the body)
✔ Internal rotation of the arm – rotating the arm inward toward the body
✔ Assisting in horizontal adduction – moving the arm inward on a horizontal plane (such as during a chest fly)
✔ Helping stabilize the shoulder joint during upper-body movements
📌 Movements that activate the anterior deltoid:
✔ Raising the arm forward (such as front raises)
✔ Throwing movements (ball throws, javelin throws)
✔ Moving weights in pressing and fly exercises
✅ 💪🏻 Muscle Fiber Types
✔ A combination of fast-twitch fibers (Type II) and slow-twitch fibers (Type I)
✔ Predominantly composed of fast-twitch fibers for rapid and powerful movements
✔ This characteristic makes the anterior deltoid highly active in explosive and strength exercises like weightlifting and throwing
✅ 🏋🏻♂️ Role in Sports and Physical Activities
✔ Active in all pressing, throwing, and forward arm-raising exercises
✔ Plays a key role in strength sports, bodybuilding, weightlifting, boxing, and discus throwing
✔ An important muscle in daily activities such as lifting objects and carrying items
✅ 🧗🏻♂️ Strength and Endurance
✔ Requires high strength for pressing exercises and overhead movements
✔ Overdevelopment can lead to muscular imbalances and increase the risk of shoulder injuries
✅ 🧠 Innervation
✔ Axillary nerve (C5, C6), which controls the movements of this muscle.
✅ 🩸 Blood Supply
✔ Posterior Circumflex Humeral Artery
✔ Thoracoacromial Artery
✅ 🤼♂️ Role in Sports and Physical Activities
✔ One of the key muscles for pushing and pressing movements in bodybuilding and weightlifting
✔ Active in throwing sports, swimming, boxing, gymnastics, and pulling movements
✔ Weakness can reduce pressing strength and increase the risk of shoulder injury
✅ 🏌🏻♂️ Interaction with Other Muscles and Joints
✔ Closely connected with the middle deltoid, pectoralis major, rotator cuff muscles, and triceps brachii
✔ Weakness in this muscle can lead to excessive strain on the shoulder joint and reduced upper body strength
✅ 💉 Vulnerability and Potential Issues
✔ One of the muscles prone to inflammation and strain due to high activity in upper-body training

✅ 🧘🏻♀️ Stretching and Recovery
✔ Stretching the arm forward and across the body to improve flexibility and prevent muscle tightness
✔ Using a foam roller to reduce muscle tension and enhance blood flow
✅ Fun Fact
✔ The anterior deltoid is most engaged in throwing movements, which is why athletes in discus, javelin, and boxing typically have a very strong anterior deltoid.
