You've been through this workout before, so you should know what to expect today! The active rest you did yesterday should have helped your body recover and prepare for the work it's about to perform.
Do your best to keep moving through all the 30-second sets. It may feel like a long time, but trust me—it's all worth it.
One of the best parts about this workout is that it requires no equipment! So, even if you're in a hotel room in Hawaii, you can still do a quick workout before you go hit the beach.
