- DifficultyIntermediate
- TypeCompound · Throw
Slamming the ball downward runs the overhead pattern in reverse: you reach full extension, then your lats, abs, and shoulders accelerate the ball into the floor. Use a dead-bounce slam ball so it cannot rebound into you, and reach tall before each rep - a longer path gives you more room to build speed.
How to do the Medicine Ball Overhead Slam
- Stand with your feet shoulder-width apart, holding a medicine ball with both hands above your head.
- Engage your core and keep your back straight.
- Bend your knees slightly and forcefully slam the medicine ball down to the ground in front of you.
- As you slam the ball down, use your entire body to generate power, including your shoulders and core.
- Catch the ball on the bounce and repeat for the desired number of repetitions.
Tip: Breathe out sharply on the release and throw the whole body into it, not just the arms.

Common mistakes
- Throwing with the arms only — the throw starts with the legs and hips, then travels through the torso and out the arms; if the legs stay still, the power is gone.
- Folding at the waist — keep the back flat as you follow through and let the hips hinge so you do not fold at the waist.
- Rushing reps as conditioning — a throw is a power exercise, so reset between reps and throw each one hard.
- Wrong ball weight — a ball that is too heavy turns a throw into a push; use something light enough to move fast.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 4–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 6–12 | 90–120 s |
| Endurance | 2–3 × 12–20 | 60 s |
Throws go at the start of a session after the warm-up, before heavy lifting, while you are fresh. Pair overhead throws with broad jumps for a power block.

What can I do instead of the Medicine Ball Overhead Slam?
If you cannot do the Medicine Ball Overhead Slam, try the Single Arm Medicine Ball Slam. Each of them trains the upper back through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Medicine Ball Overhead Slam, a sensible starting point is strength: 4–5 × 3–6 with 2–3 min rest; muscle growth: 3–4 × 6–12 with 90–120 s rest; endurance: 2–3 × 12–20 with 60 s rest. Put it early in the session while you are fresh, before isolation work for the same muscles.
