There are a variety of definitions of what moderate-intensity exercise is, but it typically falls between about 70 to 80 percent of your maximum heart rate, which would be a level 4 to 6 on a 10-point perceived exertion scale. That means you are breathing harder than normal but can carry on a conversation without much difficulty and you feel pretty comfortable with what you're doing. The American College of Sports Medicine (ACSM) often recommends this level of intensity in its exercise guidelines. The lower end of this range usually incorporates the fat burning zone.
Give crosstraining a go. Whatever your workout is — whether it's a 15 minute walk with the dog or a 10K through the park — your body gets used to it. You can actually burn fewer calories when your body is familiar with the level and type of exertion it's experiencing. So to keep your body a bit off guard, try crosstraining. Consider it a good excuse to pick up that hobby you've been eying.
If you've been lifting moderately heavy weights but are still looking to drop belly fat, it's time to pick up the intensity by using heavier weights and cutting down on rest time between reps, says Tyler Spraul, CSCS, a certified strength and conditioning specialist and the head trainer at Exercise.com. "Lifting heavy is where you see more an afterburn effect. Your body continues to burn calories even after you leave the gym," Spraul says. Just be sure that your technique doesn't suffer as you increase your weight, which can lead to injury. If you're new to strength training, this 15-minute total-body workout is a great place to start.
Break up your workouts. Your metabolism spikes after every bout of physical activity. So if you can break up your hour workout into two half-hour chunks, you'll get two spikes instead of one. Your body burns calories at a higher-rate after a workout (sometimes for several hours after), and if you rejuvenate it later in the day, you'll further enhance the effect.
There's no way around the fact that, when it comes to burning more fat, you have to work at it. There is no magic exercise, workout, or pill that will do the job for you. The good news is that it doesn't take much activity to push the body into that fat burning mode. Try incorporating some type of activity every day, even if it's just a quick walk, and build on that over time as it becomes more of a routine. Do that and you're on the way to burning more fat.
