Inch worms (not the insect) are a great dynamic stretch to perform before or after a workout. Begin this stretch by getting into the downward dog (yoga) position. Next, walk your hands forward away from your feet. Keeping the chest tight, you should get into a plank position. Then walk your feet up to meet your hands. Repeat several time. An added bonus is to do an upward dog prior to entering the plank position.
Add 5-10 inchworms to before or after next workout to help increase blood flow from head to toe!
