If you're serious about losing weight in a month, you're going to have to hit the ground running. The first week of our four-week get-lean workout plan combines strength training with cardio to make sure you cover all your bases when trying to lose fat.

By lifting, you'll build larger muscles, which translates to a higher metabolism. And by doing plenty of calorie-burning carb work, you'll improve your overall baseline fitness and get in shape for spring.

Of course, remember that a proper diet is essential to losing weight as well. You can't outwork a bad diet.


For Monday, Wednesday, and Saturday, complete the exercises in order.

For Tuesday and Friday, do a five-minute warmup before the interval workout. After the workout, do a five-minute cooldown.
