Medicine Ball Slam
The medicine ball slam is an explosive throw: you lift a non-bouncing ball overhead and drive it hard into the floor. It works the abdominals and lats, and it is used mainly for conditioning and power-endurance.
Also called: Ball Slam, Slam Ball, Med Ball Slam, Overhead Slam · Equipment: medicine ball · Pattern: compound
Step by step
- Use a non-bouncing slam ball. Stand with your feet about shoulder-width apart, holding the ball at your waist with both hands.
- Lift the ball overhead to full reach, rising onto your toes and extending your hips so your body is tall.
- Brace your trunk and pull the ball down hard, with your lats driving the arms down as your trunk bends forward.
- Push your hips back and bend your knees as the ball comes down, releasing it forcefully into the floor just in front of your feet.
- Keep your back long through the follow-through. The ball lands dead rather than bouncing back.
- Squat or hinge down with a flat back to pick up the ball, stand tall and go straight into the next rep.
- Reach tall, then rip it down
- Lats and abs together
- Hips back as the ball drops
- Throw it through the floor
- Flat back to pick it up

What goes wrong, and the fix
Arms-only slam
Fix: Drive the ball down with your lats and trunk together, not just your arms.
Rounding the back at the bottom
Fix: Push your hips back and bend your knees as the ball goes down.
Short overhead reach
Fix: Reach fully overhead and rise onto your toes before each slam.
Using a bouncing ball
Fix: Use a dead, non-bouncing slam ball for every set.
Rounded-back pickup
Fix: Squat or hinge down with a flat back to pick the ball up between reps.
Slowing down through the set
Fix: Keep every rep at full speed and end the set when slams slow down.
What the research says
General fitness · first choiceFat loss & conditioning · first choicePowerSport performanceEndurance
- Conditioning — Slams are widely used in circuits and conditioning work because there is no catch between reps. There is no direct research on slam-based conditioning.
- Load — Research on power output finds that in ballistic movements peak power occurs at light loads, which is why slam balls are usually light enough to move fast.
- Intent — Studies of velocity-specific training find the adaptation follows the intent to move fast, so each slam is typically thrown at full effort.
- Sets — A common approach for power is 3–5 sets of 5–8 slams with full rest; for conditioning, work intervals of 20–40 seconds are common. Neither scheme has been compared in research.
