Here you are, standing in a sea of cardiovascular equipment at the gym — rows upon rows of treadmills, elliptical machines, stair steppers, rowing machines, stationary bikes, and more.

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. People with knee pain are often steered toward these bikes, since the impact of body weight is not a concern as it is on a treadmill, elliptical trainer, or stair stepper.

But to avoid knee strain, you must make sure the bike is adjusted to fit your body, Vukovich says. Most people sit too low, meaning their knees flex too much as they pedal. This can put too much pressure on the knee and result in soreness, warn Vukovich. The stationary bike is a less intense calorie-burner than some of the other machines.

You'll need to pedal four miles to burn calories, says Alexander. Rowers are more advanced cardiovascular machines. Because you must push with the legs while you pull with the arms, rowers require coordination. Is it stress , anger, anxiety , or depression in a certain part of your life? Or is food your main reward when something good happens? Next, try to notice when those feelings come up, and have a plan ready to do something else instead of eating.

Could you take a walk? These are the sugars in cookies, cakes, sugar -sweetened drinks, and other items -- not the sugars that are naturally in fruits, for instance. Sugary foods often have a lot of calories but few nutrients. Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index for instance, asparagus is lower on the glycemic index than a potato or lower in carbs per serving than others.

Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. There are vegetarian and vegan sources nuts, beans, and soy are a few , as well as lean meat, poultry, fish , and dairy.

Most Americans get enough protein but could choose to get it from leaner sources, so you may already have plenty in your diet. Your exact protein needs depend on your age, gender, and how active you are. Make friends with good fats. The better choices are those in fish , nuts, and seeds, and olive oil or coconut oils. Those have unsaturated fats -- polyunsaturated or monounsaturated fats, specifically.

Fill up on fiber. You can get that from vegetables, whole grains, fruits -- any plant food will have fiber. Some have more than others. Top sources include artichokes, green peas, broccoli, lentils, and lima beans. Among fruits, raspberries lead the list. If you eat times a day, it could keep hunger at bay. You could split your calories equally across all of those mini-meals, or make some bigger than others. What About Meal Replacements? These products will control your calories.

One easy way to lose weight quickly is to cut out liquid calories, such as soda, juice, and alcohol. Replace them with zero-calorie drinks like lemon water , unsweetened tea , or black coffee. Diet drinks will save you calories, compared with sugary beverages.
