Medicine Ball Plank Tap
Every reach shifts your base to three points of contact, and the core must resist the hips rotating or dipping toward the free side. That anti-rotation demand is the whole point; the tapping is just the trigger. It builds a stable, twist-proof trunk that carries over to carries, push-ups, and unilateral work.

How to do it
- 1
Set up in a high plank with hands under the shoulders and a medicine ball placed just in front of one hand.
- 2
Brace the abs and squeeze the glutes so the body is a straight line.
- 3
Lift one hand and tap the top of the ball, then return it to the floor.
- 4
Keep the hips level and square to the floor the entire time.
- 5
Alternate hands, moving the ball across as needed, without rushing.
- 6
Stop the set when the hips start to sway or sag.
Tips
- Widen the feet for a more stable base if the hips rock too much.
- Move slowly; speed hides the rotation you are supposed to resist.
- Keep the neck long and gaze slightly ahead of the hands.
Variations
Common mistakes
- The ball sits too far out in front, so reaching it stretches the supporting shoulder and shifts your weight back over the feet instead of staying over the hands.
- A tap landing on the side of the ball rolls it away, and the next rep is spent chasing it rather than holding the plank; aim for the top and touch it lightly.
- The supporting hand creeps in toward the midline to buy balance, which narrows the base and loads the wrist at an angle it does not enjoy.
- Once one hand leaves the floor the hips rotate open toward that side, which is the exact movement the drill exists to prevent; the belt line should stay parallel to the floor.
- Shuttling the ball across to the other side mid-set is where the hips sag most, because the reach gets long and the plank gets forgotten for a second.
Frequently asked
- How many taps per hand should you do on the medicine ball plank tap when you are new to the exercise?
- Two or three sets of 8 to 10 taps per hand at roughly one tap every two seconds, with a minute of rest. End the set when the hips begin to rock rather than finishing the number you planned. Progress by bringing the feet closer together or by pausing with the hand resting on the ball for a two-count, instead of piling on more taps.
- Do I need a medicine ball for the plank tap, or will something else do?
- Anything you can touch without knocking over works: a shoe, a water bottle, a rolled towel, a book, or a cone. A taller object lengthens the reach and makes the drill harder, which is worth knowing if all you have is a small ball. Plank shoulder taps, where you tap the opposite shoulder, need no object at all and ask for the same refusal to twist.
- What is the medicine ball plank tap good for, and when is it not the right pick?
- It builds a trunk that stays square when one arm is busy, which is what carrying a bag in one hand, pressing a single dumbbell, or running actually asks of it, and it costs nothing to set up. It is a poor choice if the high plank bothers your wrists, since every tap puts your upper body on one hand; a bird dog from the forearms asks for similar control without that. It will not add core size either, because the load never rises. Build a still 30-second plank first.
