One Arm Slam (with medicine ball)
Engage your obliques and core with the One Arm Medicine Ball Slam, a dynamic exercise that builds rotational power and core stability.
Description
A high intensity exercise where you slam a medicine ball to the ground using one arm, working your arm, shoulder and core muscles.
How to Do One Arm Slam (with medicine ball)
- 1Setup
Stand with your feet shoulder-width apart, holding a medicine ball in one hand at shoulder height. Keep your core braced and knees slightly bent.
- 2Setup
Raise the medicine ball overhead with a straight arm, slightly rotating your torso towards the arm holding the ball.
- 3
Initiate the slam by powerfully rotating your torso downwards and across your body, driving the ball towards the ground beside your opposite foot.
- 4
Explode through your core and arm to slam the medicine ball into the floor as hard as possible, exhaling forcefully at the point of impact.
- 5
Catch the rebound of the ball and immediately return to the overhead starting position with control, inhaling as you reset for the next repetition.
Tips
- Focus on generating power from your obliques and core rotation, rather than just arm strength, to maximize muscle engagement and build rotational power.
- Use a medicine ball that allows for explosive movement but is heavy enough to provide resistance and challenge your core effectively.
- Maintain a slight bend in your knees throughout the movement to absorb impact, protect your joints, and allow for a more athletic stance.
- Keep your eyes focused on the point where you intend to slam the ball to help guide your movement and maintain balance throughout the explosive action.
Common Mistakes
- ×Using too much arm strength instead of core rotation will limit the exercise's effectiveness; focus on twisting your torso powerfully to drive the ball down, engaging your obliques.
- ×Not fully extending overhead at the start of each rep reduces the range of motion and power generation; ensure you raise the ball completely overhead to maximize the movement.
- ×Slamming without control can lead to injury; control the descent and catch of the ball, avoiding uncontrolled flailing that compromises form.
