High intensity interval training (HIIT) is a well-documented strategy for improving health, building lean muscle, burning fat and increasing endurance. A HIIT workout alternates between short work intervals (70 to 90 percent max heart rate) and rest periods (60 to 65 percent max heart rate).
Does HIIT increase resting heart rate?
The result showed that HIIT decreased significantly the resting HR (p=0.03), and the systolic (p=0.006) and diastolic (p=0.03) BP; also MICT decreased these parameters but they were not significant. However, there was no significant difference between HIIT versus MICT.
What should your heart rate be while doing HIIT?
“HIIT intervals should get you up to at least 85 percent of your heart rate reserve [during work periods],” Walrod said. “Then you should allow your heart rate to come all the way back down to 55-60 percent.” HIIT is not for the faint of heart.

How long does heart rate stay elevated after HIIT?
The more intense the exercise is the longer it will take for heart rate to return to its resting rate. With low-moderate intensity aerobic fitness training (as indicated in the graph) heart rates return to normal within 10-20 minutes. Stroke volume returns to resting levels in an identical fashion.
Is HIIT better than cardio for heart?
“HIIT is a time-efficient strategy to get the benefits typically associated with longer bouts of traditional cardio,” Gibala told Vox. Of course, the more you put into a HIIT workout, the more heart health benefits you get out.
