I know most people turn to cardio to burn fat but I'm not really a huge fan of doing zone-out cardio workouts such as walking, jogging, biking, swimming, elliptical training, etc. where you just sort of put your body through the motions and tune out mentally. While I do think zone-out cardio workouts serve a great purpose for relieving stress or just having fun and doing something active, I don't think doing this sort of cardio to burn fat is the best way to go about things.
Cardio to Burn Fat:
Interval training is a well-known super time efficient way to burn fat fast by alternating between high intensity cardio "spurts" and lower intensity recovery periods. However, "cardio-sculpt" workouts are also highly effective...and a tiny bit more fun too!
Cardio sculpt workouts get your heart pumping (which burns a lot of calories and fat) but also incorporate low-weight, high repetition resistance exercises to tone and sculpt your muscles. This type of workout is an amazing method of getting an overall body-toning, strength workout and fat-burning/ calorie-burning cardio workout all at once. With cardio-sculpt workouts you don't necessarily need to do high-impact exercises that stress your joints either. In fact, a cardio sculpt workout can be completely no-impact and yet still be highly effective at burning fat and calories.
Fitness trainer Ivy Larson says cardio exercising is more than walking, jogging, swimming, etc. In the video she shares some great cardio sculpt workouts which can increase blood flow into the heart, tone muscles and overall body.
