Indoor cycling is a group exercise class performed on stationary bikes. During the class, the instructor guides you through simulated flat roads, hill climbing, sprints, and races, while you control resistance on your bike to make the pedaling as easy or difficult as instructed. It is a fun, vigorous cardiovascular workout. The instructor, the people around you, and the music help keep you motivated.
There is a very big discrepancy between the Kcal burned for 30 minute elliptical on your calculator, vs the cound on the machine itself. 100% difference. When my elliptical says 300 Kcal, this calculator says 679. I don’t know which is right, but the guy at the YMCA says trust the machine (though I haven’t entered ht, wt, etc). What is your take on this?
Sidelined by sneezing, sniffling and itchy, watery eyes, thanks to all the pollen in the air? Your instinct may be to close all the windows and hide until winter, but your instinct might be wrong. According to a Thai study, researchers found that walking or running—even for just 15 minutes—can reduce sneezing, itching, congestion and runny nose by up to 70 percent. Learn the speed you should walk to breathe in less pollution.
A brilliant book at all levels, Walking for Fitness is written by Nina Barough who started the Walk the Walk charity and is a power-walking guru. It covers absolutely everything, with sections on how to get started, basic walking technique, stretches and complimentary exercises, good walking shoes and clothing, cross training, food intake, related injuries, walking with children, walking while pregnant, walking for charities or in competitions and training programmes.
“The 10,000 steps goal is thought to be a realistic minimum, and it’s good, but for complete risk reduction, people should aim for more,” says William Tigbe, M.D., Ph.D., a physician and public health researcher at University of Warwick and lead author of the study showing that 15,000 steps per day can lead to greater benefits. “In our study, those who took 5,000 extra steps had no metabolic syndrome risk factors at all.”
A study conducted with 17,000 Harvard graduates showed that students who walked for at least 30 minutes every day lived longer than those who were sedentary (17). Walking may or may not activate the telomerase enzyme, which is responsible for maintaining DNA integrity, an important factor in aging, but it helps prevent many age-related problems (18).
Facultative and Microaerophile aerobes: Facultative bacteria behave both aerobically and anaerobically, according to the prevailing conditions. In reduced environments, they acquire energy via anaerobic pathways, whereas in oxidative environments, they develop aerobic pathways. The microaerophilic bacteria require oxygen but in very low concentrations.
A good way to begin is to write down a weekly exercise plan, including when you will exercise each day, and continue to do so every week for three months if you are serious about sticking with exercise but concerned about your motivation. Write down what day(s) of the week, what time of day, minutes of activity, and the activity that you'll do when setting your plan. Be as specific and realistic as possible, and remember that it's not how much you do when you start that counts but that you simply do something. Getting started is usually the hardest part. You can always add more later on.
Whatever your preferred exercise intensity, it’s also important to choose activities that you enjoy and will stick with over the long term. Walking, biking, hiking, dancing, and gardening are all great forms of aerobic exercise that you can easily integrate into your day. After all, aerobic exercise can greatly improve your health even if you perform it in shorter segments throughout the day.
Whatever makes you feel comfortable is the easy answer. There is no need for fancy spandex or workout clothes, unless that’s what you like. As you start moving farther and faster, you may want to get dedicated fitness walking clothes that wick away sweat or allow you to layer for different weather conditions, but for a beginning fitness walker, comfort trumps everything else.
Classes are great for people who like to exercise with others, who like to dance, who like music and rhythm, who want the extra motivation and energy that an instructor and class provides, and who prefer the structure and schedule of a regular class. Classes, equipment, and videos are all great ways to stay fit and healthy, but if you're limited by injury or other conditions, then aerobic exercise chair workouts may be just the thing (see resources for online vendors). The instructor leads you through a workout in a chair and it's great exercise. You might not need chair exercise, but you may have a parent or friend who does. Exercise videos and DVDs make great gifts!
Dr. Tannenberg offers another tip for incorporating intervals into your workout: “Create a new playlist with upbeat songs followed by slower songs. Alternate the songs on your playlist. When you are walking and hear a faster song, you increase your pace. When the slower song comes on, you slow down the pace a bit. This is an easy way to make your normal morning walk an interval workout.”
