Medicine Ball Rotational Throw

The Medicine Ball Rotational Throw is a plyometric exercise with a medicine ball for your abs. Share of the load in the Zulta muscle model: obliques 25%, upper abs 13% and gluteus maximus 11%.

Level: IntermediateEquipment: Medicine ball

How to do it

  1. Stand side-on to a wall about an arm's length and a half away, feet shoulder-width, ball at the hip farthest from the wall.
  2. Rotate the torso away from the wall, loading the back hip.
  3. Drive the back hip toward the wall and let the trunk rotate hard.
  4. Release the ball into the wall at waist to chest height with straight arms.
  5. Catch the rebound, rotate back to load and repeat, then switch sides.

Tips

  • Pivot the back foot so the hips turn fully toward the wall.
  • Let the hips lead and the shoulders follow.
  • Keep the arms long so the trunk delivers the power.

Common mistakes

  • Throwing with the arms while the hips stay still.
  • Bending forward at the waist instead of rotating upright.
  • Keeping the back foot planted and twisting the knee.

Share per muscle in the Zulta muscle model. The model spreads the load of one rep over 40 muscles, based on EMG and biomechanics research.

Power comes from turning the hips and trunk. The back hip pivot drives the rotation. Throwing or slamming a ball as hard as possible: the legs and hips start it, the trunk transfers it and the arms release it; which muscles lead depends on the direction.
