Hi! Is there a simple way to add a HIIT workout if you have different combinations of workout, rest periods, so that it is not a perfect circuit that is repeating? ie sometimes I will follow a workout that is 40 seconds on, 20 seconds off, other times it is 20 seconds on, 10 seconds off, and so it is not exactly consistent. I am wondering if there is a simpler way to add a custom workout of HIIT to your activities rather than programming in a play by play of each exercise?
Any suggestions would be much appreciated, thank you!
