Stretch 
This is often forgotten or neglected it is key to realigning the protein in the muscle fibres and to prevent imbalances from forming because of tight muscles.
Do one stretch for each large muscle group, or any additional stretches to help any muscles that seem to feel tight.
TIP: Always stretch, not only when you feel tight!

TIPS
Make the goal to complete one circuit through completely with no breaks and at your highest intensity. When you have accomplished this move onto 2 and so forth. 
Keep a record of time taken to complete, try to beat this the next time you try the workout.

Enjoy!
