This is it - the bonus, optional HIIT to wring out the last of the nervous energy. This workout is just 15 minutes long. Ignore the temptation to make it any longer.
Use a HIIT timer app (we like GymBoss). Each movement is 45 seconds, with 15 seconds rest. Give it everything you've got for three rounds of five exercises, and then release the rest.
