These days the term HIIT is used to describe a fairly wide range of training methods, which is why it’s not always clear what it is beyond the basics of work, rest, repeat.

 Low-intensity interval training can be as effective as HIIT – but only if you spend more time working out

Though we know exercise is important for our overall health, and that more is typically better, many of us don’t have hours a day to devote to working out.

Consider This Before You Sign Up For A HIIT Class

High-intensity workouts are all the rage, and for good reason: They burn more calories than standard cardio, can boost your endurance and and increase the elasticity of your arteries and veins, which is really terrific for your heart.

High Intensity Interval Training: What Is HIIT, And How Do You Know If You're Doing It?

If you work out, or if you talk to people who work out, you should be familiar with high intensity interval training. You probably associate it with sweating, panting, and burpees—lots of burpees.

But methods bucking this conventional take are gaining serious mainstream traction — with the scientific evidence to support some counter-intuitive conclusions.

How to Do the Shortest Workout Possible
