HIIT 15 Class!

HIIT 15 Class is an 15 min High Intensity Interval Training workout.  There are 3 different combos that you do 3 times each.  Chalene first teaches the combo and then you do the combo 3 times high intensity.  Each one is 20 to 40 seconds long with breaks in between.  They are high impact but there is a modifier showing low impact modifications.
I liked this workout because the high impact is not very long.  Before you know it, it is over.  I did have to follow the modifier on an couple of moves but mostly kept up with Chalene.  I did notice that Chalene and crew were stomping on the floor as they jump, so be mindful to land softly when you do this workout.
