Medicine Ball Slam
- Beginner
- Compound
- Rep-based
- Core
This explosive compound movement builds total-body power and core strength by utilizing a 'triple extension' of the lower body followed by a forceful downward contraction. It effectively integrates the lats and abs to transfer energy from the upper body into the ground.

Setup
- Stand with your feet shoulder-width apart, holding a non-bounce medicine ball with both hands at waist height.
- Engage your core and maintain a neutral spine with a slight bend in your knees.
- Position yourself with enough space in front of you to slam the ball safely.
How to do it
- Inhale deeply as you lift the ball overhead, rising onto the balls of your feet and fully extending your hips and knees.
- Exhale forcefully as you use your core, lats, and arms to slam the ball into the floor as hard as possible.
- Hinge at the hips and bend your knees into a partial squat as you follow through with the slam.
- Catch the ball on the rebound or quickly scoop it up to transition into the next repetition.
Form checklist
- Keep your back flat and chest up when picking the ball up from the floor.
- Ensure the power is generated from your core and lats, not just your shoulders.
- Maintain a slight bend in the elbows throughout the overhead reach.
- Slam the ball about 6-12 inches in front of your feet to ensure safety.
Pro tips
- Focus on the 'crunch' of your abs as you slam the ball down to maximize core engagement.
- Imagine you are trying to break the ball through the floor rather than just dropping it to increase power output.
Make it harder
- Perform a burpee immediately after slamming the ball before picking it back up for the next rep.
- Add a vertical jump during the overhead reach phase to increase explosive demand on the calves and quads.
