More Evidence on the Benefits of Interval Training

Interval training rocks. If you haven't been totally convinced yet read the following information as written in a Men's Health publication.

No matter what exercise you choose, there's only so much fat you can burn during, say, a 30-minute workout. And research shows that the better trained you become, the more your body's 'exercise efficiency' improves, meaning the same amount of activity burns fewer calories as time goes by. For instance, University of California, Berkeley, scientists have determined that to avoid age-related weight gain, avid runners need to boost their weekly mileage by 1.7 miles a year.

Sure, aerobic exercise burns calories. However, if you're already dieting studies show that distance running does little to further enhance fat loss. Most likely, this is because aerobic exercise doesn't boost your metabolism after your workout. But that doesn't mean cardio can't help: high intensity intervals-such as short sprints of 30 seconds or more, interspersed with a slow jog-are great for accelerating fat loss. Why? Because they're similar to weight training. After all, a 200-meter sprint challenges your lower-body muscles hard for 30 seconds or more, just like a set of 8 reps of squats. So by doing a few intervals on the days you don't lift weights, you can spike your metabolism even higher.

In other words, if fat loss is your goal, do intervals. If your just doing steady-state aerobic activity re-read the information study above. If your a runner you would have to run an extra 1.7 miles A WEEK, every single year just to stave off age related weight gain. So there's no fat loss involved. Think about how many more minutes you'd have to add to your elliptical workout every week. The elliptical is really a waste of your time to begin with, but pretty soon you would have to be on that thing for hours.

When I design workouts for clients, and the workouts of the week I post here, they include both weight training and cardio interval training mixed together in the same workout. If's efficient and very effective.

You have to get uncomfortable in order to move forward in your fat loss goals.

Know it. Embrace it. Now go out and do it.
