  • Make a note of each of your resting breathing rates.

  • This is the number of breaths you take in one minute.

  • To make this easier, time the breaths you take for only 20 seconds.

  • Write that answer down and then multiply it by 3.

  • This will give you the number of breaths you take in sixty seconds.

  • That is the same as a minute.

  • Now do an activity like jumping jacks, skipping, stepping, etc. for two minutes.

  • Take your breathing rate immediately you stop the exercise.

  • Do this the same way you took your resting breathing rate.
