The Best Ratio for HIIT Workouts
The quality of your repetitions will degrade significantly if you do a three-to-one ratio of high-intensity interval training (HIIT) and increase the probability that you'll get injured. For most people, a one-to-five ratio of 20 seconds on to 100 seconds off is better for maintaining the quality of your form and avoiding damage to your body.

The ideal ratio for HIIT depends on the exercise being performed.
1:02:46 - 1:05:24 (02:38)
Summary
The ideal ratio for HIIT depends on the exercise being performed. For exercises with a high skill component, a ratio of one to five (20 seconds on, 100 seconds off) is best to maintain proper form and reduce risk of injury. For exercises with lower skill requirements, a ratio of 30 seconds on, 10 seconds off can be used for a greater number of sets.
