Hemera/Thinkstock(NEW YORK) -- Workout enthusiasts have likely seen it offered in some form at their local gym -- the trampoline workout. But the demand for this type of fitness is so high, one fitness instructor has opened an entire studio dedicated to the workout craze.

Going to a class at JumpLife in New York City, it’s a bit like the Jane Fonda workout on steroids goes clubbing on a trampoline. The low-impact, high-intensity, 45-minute workout is done on individual trampolines primarily in the dark under disco lights and is set to club music.

Owner Montserrat Markou said the classes are so popular there are plans to open more studios next year. Why?

“The fun,” Markou said. "They [the participants] said they’re actually working out, but having such a great time. I mean, people actually leave with smiles on their face because they feel like not only did they workout, sweating coming out all sweaty, but they also feel like a kid again.”

The studio also offers classes tailored for kids as young as 5 years old. But adults -- even those who have suffered injuries -- are the ones getting the most out of class.

“It’s low impact so a lot of people who have existing injuries like knee problems, like back problems come,” Markou said. "It’s a very comfortable way of working out and getting their fitness back.”

There are three types of adults classes offered: JumpDance (the class mentioned earlier with the low lighting and club music); JumpFitness, which uses weights and focuses on strength and toning; and JumpFusion, which is 60 minutes and fuses yoga, Pilates and rebounding at a slower pace than the other JumpLife classes.

Markou said jumpers can burn up to 600 calories in just one session.

Markou got the idea for the class after her own neck injury inspired her to become a licensed acupuncturist and massage therapist. Her clients at her Long Island practice began asking her how to get back in shape without aggravating their injuries.

Walking by a store one day, she saw a trampoline in the window and instantly knew the answer.

iStock/Thinkstock(NEW YORK) -- Ebola continues to dominate the news with the latest diagnosis of a patient in New York City, leaving many Americans on edge, especially New Yorkers, who awoke this morning to learn that the patient had take three subway lines before he was diagnosed.

So, what are the odds of catching Ebola on the subway? Here are a few Ebola facts to calm your nerves:

"There are fundamental things we do know about Ebola and it's those things that can make most people in America rest very well at night that they don't have a risk of contracting this disease,” said ABC News chief health and medical editor Dr. Richard Besser during a recent ABC News Ebola town hall event.

What If I Stand Next to Someone with Ebola on a Subway?

You probably won't catch it in that situation, Dr. Jay Varma, New York City’s deputy commissioner for disease control, said during the town hall event.

"Casual contact like you would have somebody pass you on the bus or on the subway, I’m not worried about it for myself and I’m not worried about it for my wife and kids," Varma said.

When Does Ebola Become Contagious?

Ebola is contagious when someone is symptomatic, Besser said. A fever is the first symptom of Ebola, which means the virus is beginning to multiply in the patient’s blood when a fever sets in.

As an Ebola patient gets sicker and sicker, the amount of virus in his or her blood multiplies, making them even more contagious.

How Is Ebola Spread?

Ebola is spread through close contact with an infected person, and it’s not airborne, Besser said.

“We also know from the studies in Africa that it’s a hard disease to get,” Besser said. “If this disease was spread through the air or was spread easily -- that you could get it from someone you’re standing next to in the market or sitting next to on a plane -- this outbreak would be far larger than it is today.”

People who contract Ebola usually do so because they've cared for someone who was infected in a hospital setting or at home, Besser noted, or they've touched the body of a person who died of Ebola.

Can It Become Airborne?

“The majority of scientists say that while it’s possible, it’s highly unlikely,” Besser said, explaining that the virus would have to mutate significantly.

What If Someone with Ebola Sneezes on Me?

Sneezing is not a symptom of Ebola, Besser said. Neither is coughing until the very late stages of the disease, when the person is clearly sick and near death. On top of that, the disease is not airborne.

How Long Can the Virus Survive on Surfaces Like Tabletops and Doorknobs?

“This is one of these areas where we don’t really know enough,” Varma said. “We do know that these viruses can survive on surfaces for a few hours.”

He said how long it can survive depends on the surface and the environment.

Should You Take Precautions Before Taking Public Transportation?

“We think this is not a disease that you can get from simply being next to somebody,” Varma said. “Absolutely if somebody vomits on you or you get their body fluids on you, of course you can be at risk, but we think that airplane travel, traveling on subways -- all of that -- is the type of contact where this is not a disease that's transmitted.”

He said he’s more worried about getting the flu on public transportation than Ebola.

Can I Get Ebola From Someone’s Sweat?

There’s very little data on how much of the virus is in a sick person’s sweat, Besser said.

He added that carrying a person who is sick with Ebola can be a “risky situation.” He said one man who had Ebola on a plane didn't spread it to fellow passengers but inadvertently gave it to the people who helped carry him once he got off the plane.

“Touching the skin -- whether he had other body fluids or sweat on his skin at that point -- was a risk,” Besser said.

Can Ebola Be Spread Through the Water Supply?

Ebola is not a water-borne disease, according to researchers at the Water Research Foundation. Therefore, it cannot spread through the water supply.

“Once in water, the host cell will take in water in an attempt to equalize the osmotic pressure, causing the cell to swell and burst, thus killing the virus,” the foundation noted in a statement.

Bodily fluids flushed by an infected person would not contaminate the water supply, the statement went on to say, because the virus is so fragile. Once separated from its host it is neutralized within minutes.

Can Ebola Be Used as a Terrorist Weapon?

Ebola could theoretically be used by terrorists but it is unlikely, Varma said.

Studies suggest that Ebola could in theory be delivered in mist form by spraying it out of an aerosol can. However, since the virus is not known to take an airborne route, this would likely be ineffective.

It is also possible that a terrorist willing to be infected with the virus could walk among the general population. However, since the virus has a long incubation period and is not highly contagious until the later stages of the disease, most experts say this would be impractical.

Can Ebola Be Spread by Mosquitoes?

Neither mosquitoes nor rats can spread Ebola, Besser said. "Not all viruses are adapted to survival and transmission through every vector," he noted.

Only mammals such as humans, bats, monkeys and apes have shown the ability to spread and become infected with the Ebola virus, according to the U.S. Centers for Disease Control and Prevention. Other studies have shown that dogs and pigs can be infected with the virus but they don't show symptoms and there are no known cases of these animals passing the virus along to humans.

Is There a Vaccine Coming?

There are two vaccines being tested in clinical trials now, Besser said.

“There’s a lot of efforts underway to try and move a vaccine forward but vaccine development takes a long time,” he said, adding that one of the companies working on one has said it won’t know whether it works until 2015.

Even if it does work, it will take more time to manufacture.

What About Other Drugs?

Ebola patients in the United States are receiving experimental drugs, but it’s not yet clear whether they've helped, hurt or made no difference in those patients’ outcomes, Besser said.

Why Don't We Just Close Our Borders to West Africa?

Keeping people from leaving the Ebola-affected countries would be a "major mistake," Besser said, noting that he saw aid workers, journalists and family members aboard his plane on his two trips to Liberia in the last few months, and that letting them in and out is important.

"You want to make sure that people who leave that area are being monitored and doing it safely," he said. "You want to encourage people to go there who have expertise and can help these governments, these health workers, control this disease. That will save lives there and will also improve the health and protection of Americans right here."

Varma said the biggest concern in America should be containing the outbreak in Africa. Until that happens, he said "we will always be at risk."

"You can't just wrap a wall around these countries and not expect people to get out," he said.

Brad Barket/Getty Images for NYCWFF(NEW YORK) -- There's a reason why Sunny Anderson isn't keen on eating vegetables and it has nothing to do with personal taste.

The Food Network star revealed that for the past 20 years, she's suffered from ulcerative colitis, a chronic disease that affects the large intestine and doesn't allow her body to absorb nutrients as it should. Unfortunately, greens, along with vegetable and fruit skins, can trigger flare-ups.

"I can’t just have a big salad because my body doesn't break it down," she explained to ABC News. "If you get my cookbook, there are only four vegetable recipes. Everything else is meat and potatoes!"

Anderson, 39, has since teamed up with the the Crohn's & Colitis Foundation of America to raise awareness of the disease and develop recipes (available on getyourfullcourse.com) to help others who have it. For the chef, her diagnosis came at age 19, after suffering from cramps "worse than that time of the month" and bloody stools for a month.

"I was thinking it was stress or the food [I'd been eating in Korea]...but luckily my dad is a doctor and I felt comfortable talking to him," she said.

"Sometimes people think it's something they ate or stress," she added, "I can't tell you how many times I cried. Thank goodness [for my father] who was a doctor and we were raised in an open family, but going through a battery of tests was really, really tough."

Now, she's encouraging others who have noticed symptoms to see their doctors, though she admitted discussing stools and other symptoms can be "embarrassing."

Still, a colitis diagnosis doesn't necessarily mean those who have the disease need to change their diets completely -- they just need to be more mindful of what they're eating.

"A wedge salad is one of my favorites. Argula is one of my favorites. Sometimes, you know what you're doing to yourself and you pay for it," she said. "But it's important to know what it is, and what the symptoms are."

iStock/Thinkstock(ORANGE, Calif.) -- Land of the free…home of the brave? Not, if a new survey from Chapman University can be believed.

Researchers conducted a poll of 1,500 people on what Americans are scared of and judging by the results, our fears are many and cover a lot of ground.

For instance, when asked what they feared most, Americans listed in this order:

  1. Walking alone at night
  2. Becoming the victim of identity theft
  3. Safety on the Internet
  4. Being the victim of a mass/random shooting
  5. Public speaking

Perhaps not as intense as genuine fear, next came things people are most worried or concerned about:

  1. Having identity stolen on the Internet
  2. Corporate surveillance of Internet activity
  3. Running out of money in the future
  4. Government surveillance of Internet activity
  5. Becoming ill/sick

Then, of course, there are things completely out of our hands, such as natural disasters. The most feared are:

  1. Tornado/hurricane
  2. Earthquakes
  3. Floods
  4. Pandemic or major epidemic
  5. Power outage

Meanwhile, everyone’s worried about crime and a majority believe that things have grown worse over the last 20 years even though FBI and police statistics show most crime categories have declined over the past two decades.

iStock/Thinkstock(BOSTON) -- What’s up, Doc? Certainly not Americans’ trust in physicians, according to an analysis by the Harvard School of Public Health in Boston.

Co-author Robert Blendon says that faith in doctors has eroded significantly over the past half-century. In 1966, three out of four people had “great confidence in the leaders of the medical profession.”

As of 2012, just 34 percent expressing a great deal of confidence in physicians.

In a separate poll that covered 29 nations, respondents were asked if they agreed with the statement: “Doctors in your country can be trusted.” The U.S. ranked 24th with 58 percent agreeing.

So what happened over time to make Americans less trusting of those they trust with their care? For one thing, many believe doctors are self-serving, compared to other countries where medical professionals advocate for public health.

There’s also the problem of too many major physician specialty groups, which fail to call for ways to benefit patients, such as reducing health care costs.

However, the news for doctors is not all gloom and doom. Blendon says that the U.S. is third behind just Switzerland and Denmark when it comes to people being satisfied with their own personal physicians. That means that trust is far higher on an individual scale rather than a collective basis.
