Medicine Ball Plank
- Progression - Intermediate Core Exercise
By placing your feet on a medicine ball you can progress the difficulty of
the
standard floor plank. This exercise is best used during an abdominal or core
exercise routine because it solely challenges your transverse abdominis
muscle. The harder the surface and the harder the medicine ball increases the
difficulty of the medicine ball plank. A medicine ball with a larger
circumference also increases the difficulty of this exercise by raising the
distance the lower body must be stabilized off the ground. The medicine ball
plank is best performed if you put the balls of your feet or the soles of your
shoes on the medicine ball.
