Suboccipital Rotation Strengthening
This essential stretch and strengthening works out the muscles behind your neck that connect your head and neck. This is the number one exercise I've ever done for the neck and will increase the definition the most. On top of this, this is an essential "prevent whiplash" exercise for anyone that is in a sport with hits, falls, etc. As a bonus, you'll ride roller coasters much easier ;) More on the Suboccipital muslces here.
