The fork is not to be confused with a kitchen utensil, this ‘spinal head’ is a somewhat unique tool and is only recommended for targeting the muscles on either side of the spine simultaneously.
Be sure to use with caution, assistance and/or with professional advice.
The fork can be used by placing its ends at either side of the spine and slowly working your way downward. Remember, do not place it directly on the spine and don’t go too far up where you might start hitting the neck area.
A sensible rule to adopt is to stop before the ball of the neck and focus the majority of the massage on the areas in the middle and lower back.
