A Better Way to Burn Fat 
 
If your weight-loss efforts seem stalled or stymied, heart-rate-based interval training may provide just the metabolic boost you need.  It’s not fair, you say: You’re eating right and you’re working out for hours every week, yet your unwanted fat is barely fazed – in fact, it’s just plain ignoring you. What gives?  Well, it could be that you haven’t yet trained your body to burn fat efficiently. Or it could be that you’ve adapted to your current program and, as a result, you’re burning fewer calories than you were a few months ago. Either way, stalled weight loss can be frustrating, but here’s the good news: Using strategic heart-rate training, you can drop those stubborn pounds.  Click here to learn a better way to burn fat.
 
Steady-State Cardio Vs. High-Intensity Interval Training
 
The best system of cardiovascular training probably isn’t the all-or-nothing approach. Rather, it’s a blend of both higher and lower-intensity cardiovascular training that’s tailored to your body and your goals.  Click here to discover why a blend of both high- and low-intensity exercise is the best system of cardiovascular training. 
 
Three heart-rate-based workouts that help you lose weight smarter and faster.
 
At some point in your fat-burning endeavors, you’ve probably been directed to take your pulse for a few seconds, then multiply that number to get your beats per minute. Perhaps you’ve grabbed the sensors on a treadmill to find out how hard you’re working — or just out of pure curiosity. And when you do, do you ever wonder: What’s the point? Can knowing your heart rate really help you reach your weight-loss goals? If you’re trying to drop unwanted pounds, not win a triathlon, does all that heart-rate stuff really matter?  Wonder no more: The answer is yes. It turns out that a fitness-by-numbers approach can churn out remarkable weight-loss results. It helps you upgrade your fitness, too, of course. But even if you don’t give a fig about fitness, heart-rate training is still a fat-blaster’s best friend.  Monitoring your heart rate helps you avoid the common mistake of always training in the same “gray zone” of intensity, says Troy Jacobson, head endurance sports coach at Life Time Fitness in Chanhassen, Minn. And that means you avoid wasting time and energy on workouts that don’t deliver the results you’re after. “Heart-rate training allows you to precisely control the intensity of your workouts to ensure you get the benefits you’re seeking — including fat loss.”  For more information on how to get started, click here
