Wood chops are used to exercise the obliques and medicine ball wood chops
simply use the med ball as resistance to increase the demand on the obliques
muscles. Medicine ball wood chops are probably only going to be used during an
abdominal and core exercise session. There are a variety of different form to
wood chop exercise, which to use depends on your fitness goals. If your goal is
to strengthen and tone the abdominal region, medicine ball wood chops are best
performed by trying to keep a rigid as possible torso and upper body, forcing
your to stabilize all your core muscles. If your goal is sport performance and
are looking to increase explosive rotational power, you will want to makes these
more of a full body exercise with movement at all joints as power is transferred
to and from each joint. Increasing the difficulty of the medicine ball woodchop
can be done by either using a heavier medicine ball, or increasing the
instability of the surface. You can do this by simply putting both of your feet
toegether or standing on an unstable surface such as a wobbly board or BOSU
balance trainer.
