💠 Exercise guide

The medicine ball slam is an explosive, full-body movement in which the ball is forcefully slammed to the ground. This exercise not only boosts core power but also helps release tension and enhances agility and overall body coordination. Proper execution requires strong core control and high-speed, continuous movement.

Overhead Slam

💠 How to perform the exercise

Medicine Ball Slam

Preparation

✅ Feet hip-width apart
✅ Medicine ball held in hands in front of the chest
✅ Core engaged, knees slightly bent, eyes forward
✅ Deep breath before the explosive movement

Execution method

✅ Raise the ball overhead (stretching motion engaging the back and shoulders)
✅ With control, power, and speed, slam the ball straight down to the ground
✅ As you slam, hinge the torso forward and keep your core tight
✅ Immediately pick up the ball and repeat without pausing
✅ Exhale forcefully during the slam, inhale as you retrieve the ball

Coaching tips and recommendations

✔ Use a dead ball (non-bouncing medicine ball)
✔ Avoid excessive arching of the lower back
✔ Do not lift with your back – hinge at the hips
✔ Combine explosive power with control, not reckless speed
✔ Perform 8 to 15 reps per set, depending on the program’s goal

Benefits of the exercise

1️⃣ Full activation of the core muscles
2️⃣ Increased explosive power in the torso
3️⃣ Improved reaction speed in combat and ball sports
4️⃣ Release of neuromuscular and mental tension
5️⃣ Elevated heart rate and high calorie burn
6️⃣ Practical alternative to traditional ab exercises in a standing position
7️⃣ Functional training with real-life application
8️⃣ Suitable for HIIT, CrossFit, and general conditioning
9️⃣ Can be performed at home or in the gym
🔟 Combines strength and cardio in a single movement

5 Practical Scientific Tips

1️⃣ Slam movements enhance reactive power in the core.

Source: NSCA Essentials of Strength Training and Conditioning

This exercise, by generating high force in a short amount of time, compels the core muscles to respond quickly and effectively. The combination of speed and power at the moment of the slam directly engages the nervous system.

📝 Translation: Explosive movements like medicine ball slams effectively enhance the ability to transfer force from the core to the upper limbs.

2️⃣ Slam exercises are one of the best options for stress relief and sympathetic nervous system activation.

Source: ACE – Medicine Ball Workouts

The burst of energy during the slam not only burns calories but also helps release negative emotions, reduce anxiety, and trigger the release of feel-good hormones.

📝 Translation: Exercises like slams are among the few that simultaneously provide emotional release and strengthen the abdominal muscles.

3️⃣ Medicine ball slams show high EMG activity in the rectus abdominis muscle.

Source: NSCA Research Journal

EMG studies have shown that during the slam movement, the electrical activation of the abdominal muscles is highly intense—often greater than that of traditional core exercises like crunches.

📝 Translation: Medicine ball slams have shown the highest abdominal muscle activation in EMG studies, comparable to dynamic planks.

4️⃣ This movement has high transferability to sports movements.

Source: NSCA Guide to Program Design

Slam is a “full-body ballistic” exercise that combines strength, balance, and coordination, and is directly transferable to sports like football, basketball, MMA, and volleyball.

📝 Translation: Medicine ball slams are listed by NSCA as one of the best exercises with high transferability to explosive movements and team sports.

5️⃣ High calorie burn in a short amount of time.

Source: ACE Metabolic Training Report

In an ACE study, it was found that slam exercises can burn up to 15 calories per minute, depending on body weight, intensity, and number of repetitions.

📝 Translation: Medicine ball slams, due to their explosive nature, are considered one of the highest energy-consuming movements and hold a special place in fat-burning programs.

💠 Muscles engaged in the movement

In the phase of lifting the ball, the latissimus dorsi and deltoid muscles play an active role. In the slamming phase, the abdominal muscles (rectus abdominis and obliques) are the main force generators. The stabilizers of the lower back and pelvis maintain the body’s balance.

Rectus Abdominis (Six-Pack Muscle)

Rectus Abdominis Muscle

The rectus abdominis is one of the most important muscles in the anterior abdominal wall, located vertically on both sides of the linea alba. This muscle is responsible for flexing the trunk, stabilizing the spine, and compressing the abdominal viscera.

The “six-pack” appearance seen in athletes results from the presence of tendinous intersections on this muscle. Strengthening the rectus abdominis through bodybuilding, gymnastics, and martial arts exercises significantly improves overall body performance.

✅ Effective exercises for this muscle include crunches, leg raises, planks, and ab wheel rollouts, which help strengthen its power and endurance.

Latissimus dorsi muscle

Latissimus Dorsi Muscle

The latissimus dorsi is one of the strongest and widest superficial back muscles, playing a crucial role in pulling movements, backward bending, and internal rotation of the arm. It extends from the lower spine to the humerus and is responsible for generating pulling force in exercises like pull-ups, swimming, and rowing. Strengthening this muscle enhances pulling power, improves body posture, and reduces the risk of lower back and shoulder injuries.

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.

Triceps Brachii Muscle

Triceps Brachii Muscle

The triceps brachii is one of the strongest muscles at the back of the arm, primarily responsible for elbow extension and generating power in pushing movements. This three-headed muscle (long, medial, and lateral heads) is located on the back of the arm and attaches to the ulna bone in the forearm.

✅ Why is this muscle important?
✔ The sole muscle responsible for elbow extension and essential in strength movements.
✔ Stabilizes the elbow and shoulder joints during pressing exercises like the bench press.
✔ Directly impacts strength gains in bodybuilding, gymnastics, boxing, and weightlifting.
