Your routine needs to be a total of 5 minutes long. You can take quick breaks between exercises but keep it moving! You need to have at least 4 different exercises (1 for upper body strength, 1 for core, 1 for cardiorespiratory endurance and 1 for flexibility). Remember you can include sets when doing certain exercises instead of time. For example, if you want to do the plank, you could say plank- 2 sets of 30. That means you would do the plank two times for 30 seconds each time, with a quick break in between.
