Study: breaking up your workout is more efficient

When you hit the gym do you work hard for hours on end or do you work out a little at a time? New research shows that taking a break during your exercise routine actually helps you burn more fat and increase your fat metabolism. American adults are advised to get at least 30 to 60 minutes of physical activity each day. People have often wondered: is it better to do your exercise in a single hour or should you break it up into smaller chunks? Researchers in Japan sought to answer this question by putting young men through two kinds of work out routines. In one part of the study the volunteers rode an exercise bike for 60 minutes with no break. In another part, the men rode the bikes for 30 minutes, took a 20 minute break, and then continued exercising on the bikes for an additional 30 minutes. Doctors took periodic blood samples from the men during and after their workouts. They found that there was a greater breakdown in fat when the men rested during exercise. The participants also had lower blood sugar levels when they took a break. Researchers conclude that simply lengthening your amount of exercise may not be the best way to burn fat, and that splitting up your routine could actually improve your fat metabolism.
