Medicine Ball Slams
The medicine ball slam is an explosive full-body exercise where you lift a ball overhead and throw it into the floor as hard as you can. It trains power through the core, shoulders, lats and hips, and works as a conditioning finisher because each rep is short, intense and easy to repeat at speed.
Also known as: Ball slams, Med ball slam, Overhead ball slam

What muscles does the medicine ball slams work?
Primary movers
- Rectus abdominis
- Latissimus dorsi
- Anterior deltoid
Assisting muscles
- Triceps brachii
- Gluteus maximus
- Quadriceps
- Obliques
The slam begins overhead, so the shoulders and lats stretch and then drive the ball down. The lats are the main power source for the throw, pulling the arms down and forward.
The abs flex the trunk to follow through, while the glutes and legs drive the hips into the hinge. The more the hips and torso join, the harder you can throw.
The exercise is explosive. The goal is to generate force quickly rather than lift a heavy load, which trains fast-twitch fibres and conditioning together.
Because the ball is thrown rather than lowered, there is little eccentric load on the muscles. That makes it easy to recover from, even at high effort.

Common medicine ball slams mistakes
Using only the arms
A throw with a stiff body loses power and strains the shoulders.
The fix: Drive the throw from the hips and core, and follow through down toward the floor.
Rounding the back to pick up the ball
Bending from the waist with a rounded spine loads the lower back.
The fix: Squat down with a flat back and your chest up.
Using a bouncy ball
A bouncing ball can fly back at your face or force you to chase it.
The fix: Use a dead-weight slam ball and stand clear of walls.
Not extending overhead
A short reach cuts the range and the power you can produce.
The fix: Reach fully overhead before every slam.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Power | 4–5 | 5–8 | Moderate ball, max effort | 60–90 s |
| Conditioning | 3–4 | 10–15 or 30 s | Light to moderate ball | 30–45 s |
| Finisher | 2–3 | 12–20 | Moderate ball | 45 s |
Use slams early in a session for power or at the end as a finisher. Choose a ball that lets you move fast. If your ball is too heavy, you will slow down and lose the benefit. Two sessions a week works well.

Frequently asked questions
What do medicine ball slams work?
The abs, lats, shoulders, glutes and legs. It is a full-body power exercise that also challenges your heart rate.
How heavy should the slam ball be?
Most people do well with 4 to 8 kg. Choose a ball you can lift overhead and throw hard. If you slow down, it is too heavy.
Are medicine ball slams good for conditioning?
Yes. They are quick, intense and use many muscles, so they raise the heart rate. They work well in circuits and as a finisher.
Can slams hurt my back?
They are safe with good form. Keep your spine neutral when picking the ball up and avoid overextending when you reach overhead.
Which ball should I use for slams?
A dead-weight slam ball with a thick shell. A normal medicine ball can bounce and may split under repeated slams.
