If you trained on a super-heated floor you'd have to be super-light on your feet and move really fast to avoid getting burnt. The Floor is Lava is just the kind of workout that prepares you for that. Perform every exercise balancing on the balls of your feet for that added challenge, pay attention to form and move as fast as you can without sacrificing it. Go EC for the added challenge to your VO2 Max.
Extra Credit: 1 minute rest between sets.
