Is High Intensity Interval Training (HIIT)—intervals of high-intensity exercise followed by two minutes of moderate exercise— too good to be true? No, asserts Suzanne Steinbaum, DO, author of Dr. Suzanne Steinbaum’s Heart Book: Every Woman’s Guide to a Heart Healthy Life and Bottom Line’s “At the Heart of It All” blog. HIIT is a great way for people to stay fit, especially if they only have limited amounts of time to exercise. The concept is simple: Exercise at 100% intensity for 20 seconds—anything that gets the heart racing is acceptable—then do two minutes of less intense exercise for a total of 10 minutes per session. Research has discovered that HIIT is just as effective as a longer, less strenuous workout when it comes to managing heart health.
