Cardio's Best Fat Burner
So you want the bottom line: Which cardio exercise will fat-bust the best?
"Running is the best option for calorie burning, in my opinion," says Niki Kimbrough, personal fitness expert with Bally Total Fitness. "Whether it's outside or on a treadmill, it's the best exercise because you're burning calories and you're strengthening your legs and heart -- it'll get you nice and lean."
Beginners should start with 20 minutes, explains Kimbrough, and work their way up.
"It takes about 20 minutes for your body to get going, and then your body starts to kick it to another level," says Kimbrough. "Ideally, you want to run for about 30 or 45 minutes."
For those with bad knees, Kimbrough recommends the elliptical machine as a good second choice.
In case running isn't your game, Kravitz takes another track.
"I really feel the most important message is to chose a cardio modality or modalities that you like," says Kravitz. "Because in the final outcome, if a person enjoys a mode of exercise, that is what all research shows they will choose."
Splitting It Up
While it may not be the fastest way to a body built for the beach, splitting up your cardio exercise still has its benefits.
"In order to achieve the best results, and also in order to maintain a healthy heart, it is best to not split up your cardio workouts," says Austin. "You need the consistency of 20 minutes or more of an elevated pulse to ensure great results. However, something is better than nothing. If all the time you have is 10 minutes or even five minutes, it is better than sitting still; you will still be garnished benefits and lose weight."
Kick Up Your Cardio
Let's be honest -- cardio exercise can get boring after awhile. How can you jazz it up and make it interesting again? The experts recommend never letting it get stale in the first place.
"I believe you should do different types of cardio exercises during the course of a week, if possible," says Austin. "The thing to remember is that too much repetition willmuscles and you will plateau, which will slow your results down. By adding variety to your workouts you give muscle groups a chance to recover on their days off and you can maintain a steady progress."
