Research has shown that interval training—short bursts of intense exercise, followed by lighter activity—can give you the same great results as continuous moderately intense exercise, in less time.

To save you both time and money, Best Health designed the ideal seven-interval workout you can do at home. From start to finish, it takes 45 minutes, and will burn between 400 and 600 calories for a 140-lb. woman, depending on how hard she’s working.

Do this workout two to three times a week to see results in six to eight weeks—you’ll be fitter and more toned, and can potentially lose 10 pounds, if you also keep your diet in check.

So, let's get started! >>>
