Go through each workout as quickly as you can and then right into the next exercise without a break. See how many repititions you can do in a minute. Push yourself as hard as you can for four minutes then take a one minute rest. Go through the exercises 5 times! If you are feeling comfortable at any point throughout your workout, you're not working hard enough! Push yourself for 24 minutes, and you've had an amazing workout.
PS. Working on a video for your next exercise :)
