Plank Alternating Hit The Ball
- Intermediate
- Compound
- Timed hold
- Shoulders
- Waist
This dynamic plank variation builds exceptional core stability and shoulder endurance by forcing the body to resist rotation while striking a medicine ball against a wall. It engages the entire anterior chain, glutes, and deltoids to maintain a rigid posture under shifting loads.

Setup
- Assume a high plank position (hands under shoulders) facing a wall, approximately arm's length away.
- Place a medicine ball on the floor between your chest and the wall.
- Set your feet slightly wider than shoulder-width to create a stable base and prevent hip rotation.
- Engage your glutes and quads to create a rigid line from head to heels.
How to do it
- Exhale and quickly lift one hand to strike or push the medicine ball against the wall with controlled force.
- Maintain a perfectly still torso, resisting the urge to tilt your hips as you move to a single-arm support.
- Inhale as you return your hand to the starting position and stabilize the ball.
- Repeat the movement with the opposite hand, alternating sides at a steady, controlled tempo.
Form checklist
- Keep hips square to the floor; do not let them rotate or 'hike' during the strike.
- Maintain a neutral neck by looking at the floor just in front of the ball.
- Keep the supporting shoulder active by pushing the floor away, avoiding any 'winging' of the shoulder blade.
- Ensure the lower back does not sag or arch throughout the set.
Pro tips
- Focus on 'anti-rotation'—imagine a glass of water sitting on your lower back that you cannot spill.
- Squeeze your glutes as hard as possible during the strike phase to lock your pelvis in place.
- Vary the speed of the strike to challenge your reactive core stability.
Make it harder
- Narrow your foot stance to reduce your base of support, significantly increasing the demand on the obliques.
- Use a heavier medicine ball or increase the distance from the wall to require more force and stabilization.
