Why High-Intensity Interval Training Is Better
At one time, fitness gurus would tell you to get the benefits of exercise you need to work out for 30 minutes or more. Then studies came along showing you can get a cardiovascular workout in as little as 10 minutes if you work out at a high intensity. That’s when high-intensity interval training entered the scene and brief exercise became popular.
What is Interval Training?
The idea behind interval training is to alternate brief periods of very intense exercise (30 seconds to a minute) with periods of recovery (1 to 3 minutes). During the “active” intervals you give it your all-out effort and then allow yourself to recover so you could increase the intensity again and repeat the cycle.
But how effective is interval training? Studies show that 15 or 20 minutes of high-intensity interval training is more effective for burning fat than an hour of steady state cardio. There’s another bonus too. It works your most important muscle, your heart. So, these days there’s a movement away from long periods of cardio towards shorter, more intense training.
