JILLIAN'S TIP OF THE DAY
The Ins and Outs of Interval Cardio

Mixing interval cardio moves with weight training keeps your heart rate at a higher level throughout a workout. Why is maintaining an elevated heart rate important? Because it means you'll burn more calories. If you're just starting out, add a 15-second interval cardio move after every three weight exercises. As your fitness level increases, you can make your interval cardio sessions longer or add more of them to your workout.
