What Do You Want to Know About Fitness and Exercise?
When you've finished that, pedal or run at a rate that's 20 percent harder than your normal cardio intensity. While interval training is one of the most efficient ways to burn calories and fat, it's still tough to lose that pound with exercise alone.

How Much Exercise Does It Take To Lower Cholesterol?

TRAIN. MYOPLEX. REPEAT.

Slowly I stopped my exercise routine. Taking care of two kids and husband is no easy job. I cared so much whether my kids and husband are eating right and I forgot to care for myself. Trust me, cleaning out my closet for spring, was my wake-up call. That is when I decided that I have to make some changes in my life. Me being healthy and around for my family is more important than anything in this world. I said to myself that I would eat right every single day.

I tried dieting for months and have starved for days, nothing seemed to work out. Was about to give up and saw success stories of people online by using Nutrisystem. Nutrisystem was my last resort. Nutrisystem has delicious recipes loaded with protein, fiber and smart carb. 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. They also you require you to engage your core abdominal muscles to support and protect your back.

Because they use so many muscle groups, rowers burn lots of calories. But this machine has several red flags for a beginning or unfit exerciser. Extra weight often comes with back pain , and this is not a machine you want to use if you have back issues, he says. Choose a machine that feels right. If impact is a problem, the stationary bicycle may be a better choice than the treadmill.

More muscle use equals more calorie burn. The basic rule of thumb is that the machine that exercises the greatest muscle mass burns the most calories. But recent studies have more carefully examined the effect of exercise alone, making it easier to evaluate the relationship between exercise and cholesterol. Researchers now believe there are several mechanisms involved. First, exercise stimulates enzymes that help move LDL from the blood and blood-vessel walls to the liver.

From there, the cholesterol is converted into bile for digestion or excreted. So the more you exercise, the more LDL your body expels. Second, exercise increases the size of the protein particles that carry cholesterol through the blood.

The combination of protein particles and cholesterol are called "lipoproteins;" it's the LDLs that have been linked to heart disease. Some of those particles are small and dense; some are big and fluffy. Exactly how much exercise is needed to lower cholesterol has been a matter of some debate. In general, most public health organizations recommend, at a minimum, 30 minutes per day of moderate to vigorous exercise , such as walking, jogging , biking, or gardening.

But a study by researchers at Duke University Medical Center found that more intense exercise is actually better than moderate exercise for lowering cholesterol. In a study of overweight , sedentary people who did not change their diet, the researchers found that those who got moderate exercise the equivalent of 12 miles of walking or jogging per week did lower their LDL level somewhat.

But the people who did more vigorous exercise the equivalent of 20 miles of jogging a week lowered it even more. The people who exercised vigorously also raised their levels of high-density lipoprotein HDL -- the "good" kind of lipoprotein that actually helps clear cholesterol from the blood.
