Nutrisystem labels snacks as either Power Fuels or Smart Carbs. The basic rule of thumb is that the machine that exercises the greatest muscle mass burns the most calories. Calling someone too skinny can be just as painful as calling someone fat. If you're a beginner, using more muscles means getting fatigued sooner -- which will result in burning fewer calories. Seventy-five percent of those calories, or 75 calories, may come from fat.

However, a person who runs those same 15 minutes and burns calories may burn only 50 percent of those calories from fat, but will burn a total of fat calories in the same amount of time. A study based on 36 relatively fit runners published in the "Journal of Strength and Conditioning Research" in October demonstrated that determination of a person's exact fat-burning zone may only be performed in a laboratory.
In this study, significant overlap between the fat burning and cardio zones existed, indicating that a person working within 60 and 80 percent of maximal heart rate is likely to be maximizing fat oxidation. Unless you are training for a figure or body building competition where working in the fat-burning zone exclusively helps you preserve every bit of lean body mass, it is best to focus on improving fitness and calorie burn with varying levels of intensity. If you choose to work in the lower range of the cardio zone—the fat-burning zone—be prepared to work out longer to burn enough calories to affect weight loss.
Incorporating high cardio and lower cardio zone exercise into a workout routine will offer the most aerobic and weight loss benefit. Video of the Day. So which one do you choose: The machine that is supposed to get you the most fit; the one that burns the most calories; or the device that has least impact on your joints? These are all valid concerns -- but none of these is the most important question you should be asking yourself, says exercise physiologist Bryant A.
Which machine do you really want to use? So instead of choosing the treadmill for the calorie-burning factor, or the elliptical trainer your friend recommended, figure out which machine feels best to you, he suggests. Nashville exercise physiologist Kathy Alexander agrees: But how do you know which machine is likely to feel right to you? Here's what you can expect from the most popular cardio machines out there, along with some tips on getting the most out of your workout.
Here's the lowdown on what you can expect from some of the machines you're likely to find at your local gym. The treadmill burns the most calories of any of the cardiovascular machines available at most gyms, says Alexander. You can expect to burn about calories per mile, walking briskly. Stamford notes that a treadmill can be adapted to many different fitness levels by increasing the speed from walking to running or by adjusting the incline. But even walking may be too much for someone who is overweight and has joint pain.
Every time your foot hits the ground, says Alexander, "the impact forces are 3. Since a treadmill is moving under you, the impact may be slightly less than that. One more thing to keep in mind: Treadmills can pose a real balance challenge for new exercisers or those who haven't worked out in a while, says Matthew Vukovich, exercise physiologist and associate professor at South Dakota State University.
These machines pack a little less punch on the joints, and either can be a good alternative to the treadmill, says Vukovich. Because you use them in a standing position, you're using lots of muscle mass, so the calorie burn rate is still pretty high. Elliptical machines with arm components can further increase the numbers of calories you burn, says Stamford. All our experts agree that the stationary bike offers the workout with the least impact on the joints.
