Burn More Calories in Less Time

By Jenna Autuori-Dedic

Minis are in! "Shorter, harder workouts may actually be better for revving your metabolism than longer sessions," says trainer Jessica Smith, a co-author of The Thin in 10 Weight-Loss Plan. "You'll continue to burn calories at a higher rate long after you're done exercising." Here's how to maximize the minutes you think you don't have.

How to Do It
Split it up. Instead of a 40-minute slog, think of your daily cardio as four 10-minute sessions or two 20-minute workouts. "You net the benefits no matter when you get it done," Smith says.

Move before you make excuses. "Bang out a routine right after you wake up," Smith says. Set your alarm 20 minutes earlier than usual; not only will you not notice the missed sleep, but you'll also get an energy buzz from the exercise.

Push yourself. When your workout is short -- 20 minutes or less -- "going all out is much more doable, and that's what will really make your cardio count," Smith says.

The Plan: Got only 5 minutes?

Follow this do-anywhere Tabata routine from Jessica Smith. To make timing it a cinch, use the Tabata Pro app ($3, iTunes) or the pocket-size Gymboss ($20, gymboss.com) interval timer.
