Is the one minute workout for real? Here’s what you need to know about whether it’s right for you...

There’s a lot of talk in the exercise world about high intensity interval training (HIIT) lately, which is exactly what it sounds like — alternating episodes of exercise with periods of less intensive activity or recovery. It’s not an new idea, although many gyms, trainers and some experts are touting it as if it’s a new phenomenon. Professional and elite athletes have been using interval training for nearly a century to maintain their peak performance with the least wear and tear on their bodies. And it’s baked in to workouts like SoulCycle, Cross Fit and many group classes at gyms.
