Yoga Tip: Seriously Intense Ab Exercise

If you're working on core strength, or trying to tone up in time for summer, this is an exercise you should try out. It should be done three to five times with brief rests between sets. Tip: Make sure your butt is in line with your body (the tendency is for the butt to either sink really low or be up really high). Hope you enjoy! 

PS: I wrote an article about what to bring to yoga teacher training that was published on Do You Yoga, a gooey peanut butter oatmeal recipe, and a playlist for cardio exercise.
