Tuesday's Trunk and Core -- InTENse Plank Challenge

Today's workout comes from RealFitTv.  It is a HIIT (high intensity interval training) workout that alternates between 30 second cardio exercises and 30 second plank challenge exercises.  Remember you've got to burn the fat above to see those awesome muscles below!

A warm up and cool down are included, the actual HIIT workout is only about 10 minutes long, but is very inTENse!!!  Try to do the planks on your toes, but modify to your knees (butt down) if you just can't hold it any longer.  You can modify to your forearms if you have issues with your wrists.
