"Somewhere, someone busier than you is running" or doing twenty-five-minute workouts with help from Shaun T's new FOCUS T25 DVD Workout program. The eleven non-stop twenty-five-minute workouts on nine DVDs and schedule are designed to make the most out of your time and maximize results. It's a mixture or cardio and strength training and ideal for busy people who want to get fit quick but have limited time to exercise. The FOCUS T25 pretty much follows the principles of high intensity interval training (HIIT), a proven method to improve performance and get fit in a short time. The great thing about these types of programs is that when you push that play button, all you have to do is follow the workout; thinking what to do next is removed so you can focus on the twenty-five minutes. If you don't have twenty five-minutes, consider this; plenty of research has shown that exercise boosts productivity and helps you sleep better at night.
High intensity interval training (HIIT) is one of the most effective ways to get fit very quickly. Roger Bannister, the first man to break the 4-minute mile barrier and made way for others to do the same, "relied on interval sessions of ten 60-second sprints separated by two minutes of rest, because his duties as a medical student on clinical rotation limited his training time to half an hour a day at lunch" - from the book Which Comes First, Cardio or Weights?: Fitness Myths, Training Truths, and Other Surprising Discoveries from the Science of Exercise. If you're busy, HIIT might work for you.
