Triple interval training is a technique that can help you go harder and incinerate calories quickly. Here's how it works: Instead of alternating between two intervals - fast and slow, as you would during an HIIT (High Intensity Interval Training) workout - you alternate between 30-20-10 second bouts, including your burn from slow to fast to max.
So what gives this method an edge? It pushes you harder, without you even realizing it. Even when you think you're in high gear, you probably have the capacity to push a little bit more. The last interval forces you to dig deeper and find the energy you have left to complete the task and because you know it will be brief (you can do anything for 10 seconds), you muster up what is required in order to do it. Those last seconds help to spike your metabolism, help to increase your speed and endurance.
Danish runners tried it and proved the theory: They shaved seconds off their times and lowered their blood pressure, all while cutting their mileage in half. When we tested it on walkers, they lost up to 11 lbs. and more than 12 inches in 8 weeks. Try this training method with any activity you like in order to supercharge your burn.
