Best way to log cardio circuits

Hey guys!
I am looking for the best way to log cardio circuits. For example today I will be do circuits of jumping jacks, crunches, squats, wall sits, and push ups. I unfortunatly do NOT have a heart rate monitor. I have asked for one for Christmas so hopefully by the new year I can use it. But as of today I don't. I tried looking up cardio circuits but it is not an option in the log exercise. Regular circuit training is but Im not sure if that is the best one to use. Anybody else come across anything I might be able to use?
